Functors, Applicatives, And Monads in Python (source files)
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.
