+# Fun Language Specification v0.2
+
+**Fun (Fun Uses Nothing)** is a lightweight, multi-purpose programming language designed for clarity, safety, and—above all—fun.
+
+This document defines the language syntax and semantics as of version 0.2.
+
+## 1. Introduction
+
+Fun is a scripting and systems programming language inspired by the best ideas from C, Lua, and Python—yet deliberately strict in its rules to ensure readability and consistency.
+
+ - **Readable**: fixed indentation rules, no ambiguous syntax.
+ - **Strict**: type safety, no implicit coercion, no silent shadowing.
+ - **Hackable**: strong system integration with safe defaults.
+ - **Fun**: simple enough to learn in a day, expressive enough for real work.
+
+## 2. Lexical Structure
+
+### Case Sensitivity
+
+Fun is **case-sensitive**. `Hacker` and `hacker` are different identifiers.
+
+### Identifiers
+- May contain `a–z`, `A–Z`, `0–9`, and `_`.
+- Must not start with a number.
+
+### Keywords
+
+Reserved words cannot be redefined:
+`if`, `else`, `for`, `while`, `fi`, `fun`, `global`, `private`, `return`, `true`, `false`.
+
+### Comments
+
+ - Single-line:
+
+```fun
+// This is a comment
+```
+ - Multi-line:
+
+```fun
+/*
+This is a
+multi-line comment
+*/
+```
+
+### Whitespace
+
+ - Indentation is exactly two spaces.
+ - Tabs are forbidden.
+ - Line breaks terminate statements (no semicolons).
+
+## 3. Data Types
+
+### Number
+
+ - 64-bit signed integer.
+
+```fun
+number n = 42
+```
+
+#### More number like (int) data types
+
+ - int8, uint8 (8bit signed and unsigned integer type)
+ - int16, uint16 (16bit signed and unsigned integer type)
+ - int32, uint32 (32bit signed and unsigned integer type)
+ - int64, uint64 (current number stays as int64)
+
+### Float
+
+ - 64-bit IEEE floating point.
+
+```fun
+float pi = 3.14159
+```
+
+### String
+
+ - Double or single quotes may be used.
+ - ' has higher priority, so " can appear unescaped inside '...'.
+ - To include ' inside '...', escape with \'.
+
+```fun
+string s1 = "Hello"
+string s2 = 'World'
+string s3 = 'He said: "Fun!"'
+```
+
+### Boolean
+
+ - Canonical values: true, false.
+ - 1 and 0 are accepted in conditionals.
+
+```fun
+boolean flag = true
+```
+
+### Byte
+
+ - Raw byte value.
+
+```fun
+byte b1 = 0x23
+byte b2 = 'A'
+```
+
+### Array
+
+ - Declared using [ ... ].
+
+```fun
+array nums = [1, 2, 3]
+```
+
+#### Supported typed arrays:
+
+```
+array<number> nums = [1,2,3]
+array<string> names = ["Alice","Bob"]
+```
+
+#### Multidimensional arrays:
+
+array<number> matrix = [[1,2],[3,4]]
+
+ - Arrays or dictionaries can hold different types, even if scalars are strictly typed (including objects later).
+
+```
+array mixed = [1, "two", true, [3,4]]
+```
+
+## 4. Variables and Scope
+
+ - Global variables: accessible everywhere.
+ - Private variables: file-local, cannot be used outside the file.
+ - Redefining globals or shadowing names is forbidden.
+
+```fun
+global string message = "Hello"
+private number count = 42
+number nothing = 23
+```
+
+ - Dynamic variables
+
+```
+dynamic string x = 42
+x = "Now I'm a string"
+```
+
+## 5. Operators
+
+ - Arithmetic: `+`, `-`, `*`, `/`, `%`
+ - Comparison: `==`, `!=`, `>`, `<`, `>=`, `<=`
+ - Boolean: `&&`, `||`, `!`
+ - Assignment: `=`
+
+## 6. Control Flow
+
+### If/Else
+
+```fun
+if(x != y)
+  print x
+else if(a == b || h != i)
+  print a + b
+else
+  if(k < 1 && l > 1)
+    print "Buh!"
+```
+
+### For Loops
+
+```fun
+for i in range(1, 10)
+  print i
+```
+
+### While Loops
+
+```fun
+while x < 10
+  print x
+  x = x + 1
+```
+
+## 7. Functions
+
+### Internal Functions
+
+Provided by the runtime (cannot be redefined). Examples:
+print, range, system, exec.
+
+```fun
+print "Hello, Fun!"
+```
+
+### User-Defined Functions
+
+Must be declared with the fun prefix.
+
+```fun
+fun add(a, b)
+  return a + b
+```
+
+#### Functions support multiple return values:
+
+```
+fun divide(a, b)
+  if b == 0
+    return 0, "division by zero"
+  return a / b, ""
+```
+
+### Return Values
+
+ - Scalars: return a + b
+ - Arrays: return [a, b, c]
+
+## 8. Modules & Includes
+
+### System Includes
+
+Looked up in /var/lib/fun/, supporting .so (native) and .fun (Fun code).
+
+```fun
+#include crypt/md5
+#include date
+#include math
+```
+
+### Local Includes
+
+From the current working directory:
+
+```fun
+#include utils/file.fun
+```
+
+### Absolute Includes
+
+Full path:
+
+```fun
+#include /home/user/project/lib.fun
+```
+
+### Aliasing
+
+```fun
+#include math as m
+print m.sqrt(16)
+```
+
+```fun
+#include /home/user/project/universe.fun as u
+print u.size()
+```
+
+## 9. Objects
+
+## 10. Reflections
+
+```fun
+typeof(x)  // Returns "number", "string", etc.
+methods(obj)  // Lists callable methods
+```
+
+## 11. System Integration
+
+### Blocking
+
+#### exec(cmd)
+
+Executes a command, returns stdout.
+
+```fun
+string result = exec("date")
+```
+
+#### system(cmd)
+
+Executes a command, returns exit code.
+
+```fun
+system("ls -l")
+```
+
+### Non-Blocking
+
+#### nexec(cmd)
+
+Executes a command, returns a future-like object for async output retrieval:
+
+```fun
+object future = nexec("long_task")
+result = read(future)
+wait(future)
+```
+
+#### nspawn(cmd)
+
+Executes a command asynchronously, returns process ID.
+
+```fun
+number pid = nspawn("sleep 10")
+```
+
+#### nsystem(cmd)
+
+Executes a command, returns exit code.
+
+```fun
+number exit_code = nsystem("ls -l")
+```
+
+### Helpers
+
+#### wait(pid)
+
+Blocks until process finishes, returns exit code.
+
+#### read(pid)
+
+Returns captured stdout (for processes started with nexec).
+
+#### kill(pid)
+
+Terminates process.
+
+## 12. Error Handling
+
+ - No implicit type coercion.
+ - Redefinition of globals is a compile-time error.
+ - Internal/runtime functions cannot be shadowed.
+ - Compile-time: undefined variables, illegal redefinitions, type mismatch.
+ - Runtime: failed system calls, division by zero, etc.
+
+## 13. Examples
+
+### Hello World
+
+```fun
+print "Hello, World!"
+```
+
+### Loop with Range
+
+```fun
+for i in range(1, 5)
+  print i
+```
+
+### User Function
+
+```fun
+fun greet(name)
+  return "Hello " + name
+
+print greet("Fun")
+```
+
+### System Call
+
+```fun
+string now = exec("date")
+print "Current time: " + now
+```
