// Demonstration of the include-as namespace feature.
//
// Run examples (without installing) by pointing FUN_LIB_DIR to the repo lib:
//   Linux/macOS/FreeBSD:
//     FUN_LIB_DIR="$(pwd)/lib" ./build/fun examples/include_namespace.fun
//   Windows (CMD):
//     set FUN_LIB_DIR=%CD%\lib && build-debug\fun.exe examples\include_namespace.fun
//   Windows (PowerShell):
//     $env:FUN_LIB_DIR="$PWD\lib"; .\build\fun.exe examples\include_namespace.fun

// Import stdlib math helpers into alias 'm'
#include <utils/math.fun> as m

// Import a local module (this repository file) into alias 'mod'
#include "examples/namespaced_mod.fun" as mod

print("=== include-as namespace demo ===")
