Summary

Fix recursive function execution in Multilang-Python and improve CLI argument handling.

Changes

• Fix recursive function execution by using an explicit shared namespace for exec().
• Compile translated code with the source filename for more informative tracebacks.
• Add --help and -h support.
• Fix --version to exit successfully.
• Improve error handling and exit codes.
• Provide standard execution metadata (__name__, __file__, __package__).

Problem Fixed

Previously, translated Python code was executed using:

exec(translated_code)

Recursive functions could fail with NameError because their definitions were not available in the execution's global namespace.

The implementation now uses:

exec(compiled_code, namespace, namespace)

This ensures that functions, including recursive functions, can resolve their global references correctly.

Testing

Environment: Windows 11 ARM64, Python 3.14.

• Python syntax compilation: PASSED.
• CLI --help: PASSED.
• CLI --version: PASSED.
• CLI --list-langs: PASSED.
• Bulgarian recursive factorial example: PASSED.

Scope

This fix is language-independent and does not modify any language configuration files.
