## What it is
gopy is a command-line tool that generates and compiles CPython extension modules from Go packages, letting Python code call Go code directly. It uses int64 handles for safe garbage-collector interop and supports callbacks from Go into Python and struct-based class inheritance in the generated wrappers.

## Use cases
- call a Go library from Python
- generate Python bindings for a Go package
- use Go code in a Python project
- wrap a Go SDK for Python users
- expose Go functions as a CPython extension module
- run Go GUI libraries from Python scripts

## When to choose
- you have an existing Go package and want to use it from CPython
- you need tight, compiled bindings rather than a subprocess or HTTP bridge
- you need Go-to-Python callbacks and Go struct inheritance mapped to Python classes

## When to avoid
- you need PyPy support without extra work (cffi path is not the default)
- you want pure-Python packages with no compilation step
- your Go package relies on features gopy cannot wrap
