## What it is
A Clojure library providing deep bidirectional integration between the JVM and Python, allowing Clojure/Java code to call Python libraries and vice versa. It bridges JVM and Python objects with GC-linked lifetimes, efficient numpy data copies, and supports embedding a Clojure REPL inside a Python host process.

## Use cases
- call python libraries from clojure
- use numpy and pandas from the jvm
- embed clojure in a python application
- use machine learning libraries like pytorch from clojure
- bridge jvm objects and python objects
- run a clojure repl inside python

## When to choose
- you are on the JVM and need Python's ecosystem (numpy, ML libraries) without leaving Clojure/Java
- you want bidirectional interop with GC-safe object lifetimes
- you need a Java-only API to embed Python without writing Clojure

## When to avoid
- you need a pure-Python or pure-Clojure solution without cross-language overhead
- your project requires strict GIL-free high-throughput calls to many small Python functions
- you are not on the JVM platform

## Facets
