Appendix E: Module System (Future)¶

Current State: All standard library functions and traits are automatically in scope.

Future Design: A module system for organizing code and managing namespaces.

Proposed Syntax:

// Import entire module (using :: prefix)
::std::math use

// Import specific items
::std::collections::HashMap use

// Import with alias - Option 1: Inline alias
::std::io::File ::F as use

// Import with alias - Option 2: Separate alias operator
::std::io::File ::F use_as

// Import with alias - Option 3: Block syntax
{ ::std::io::File ::F as } use

// Export from current module
::Point ::geometry export
::distance ::geometry export

// Module declaration
::my_module module {
    // Module contents
}

Module Resolution:

• Standard library: ::std::<module>::<item>
• User modules: Relative to current file
• Third-party: Package manager integration (future)

Benefits:

• Clean namespaces
• Explicit dependencies
• Code organization
• Faster compilation (selective imports)
