SUMMARY="Functors, Applicatives, And Monads in Python"
DESCRIPTION="OSlash (Ø) is a library for playing with functional programming in \
Python 3.8+. It's an attempt to re-implement some of the code from Learn You a \
Haskell for Great Good! in Python 3.8. OSlash unifies functional and object \
oriented paradigms by grouping related functions within classes. Objects are \
however never used for storing values or mutable data, and data only lives within \
function closures.

OSlash is intended to be a tutorial. For practical functional programming in Python \
in production environments you should use FSlash instead."
