## What it is
nimpy is a Nim library that provides seamless bidirectional integration between Nim and Python. It lets you implement Python extension modules in Nim and call Python code from Nim with automatic type conversion.

## Use cases
- write a Python module in Nim for performance-critical functions
- call Python libraries like os or numpy from Nim code
- compile Nim code into a .so or .pyd importable from Python
- speed up slow Python hot paths with compiled Nim extensions
- integrate existing Python packages into a Nim application
- build ABI-stable Python extensions that work across Python versions

## When to choose
- you need native-speed code callable from Python without writing C
- you want to use Python's ecosystem from a Nim project
- you need extensions that are ABI-compatible across Python versions
- you prefer Nim's syntax and type system over C for Python extensions

## When to avoid
- you need deep numpy integration with zero-copy performance (consider scinim)
- your project is pure Python with no need for native code
- you need bindings for a language other than Python or Nim

## Facets
