## 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)
