The `#use` directive now supports referencing entire directories,
automatically including all `.myc` files within them. Additionally,
environments are now initialized with the current working directory as a
default search path, simplifying module resolution.
Introduces the `#use` preprocessor directive, allowing Myc scripts to
explicitly declare dependencies on other Myc libraries. This change
moves dependency management from a command-line argument to an in-script
declaration, ensuring scripts are self-contained and can correctly
resolve macros and other symbols.
Key features include:
- Declarations at the beginning of a file, evaluated before parsing.
- Support for relative paths and a new `->` separator.
- Automatic resolution of dependencies from specified search paths.
- Idempotent loading to prevent duplicate parsing and evaluation.
- No AST pollution; dependency management is a compile-time concern.
The compiler's lexer has been updated to recognize `#` as a comment
character, and the environment now manages search paths and loaded
modules. This lays the groundwork for more complex library structures
and improved code organization.
