metap: A Meta-Programming Layer for Python

Metap is a new Python package that provides a meta-programming layer enabling three key capabilities: program augmentation (automatically enhancing code with features like dynamic type checking), user-defined code generation (custom macros and statements), and structural introspection (checking code structure properties). Unlike domain-specific languages that define abstract behaviors, metap generates predictable Python code, making it transparent and debuggable. The package addresses limitations in Python's built-in meta-programming features by offering utilities for logging returns, breaks, continues, function calls, and enabling custom syntax extensions through a simple macro system.
