[Python-ideas] Quick Lambdas and Partials (Re: A suggestion for Python 3 vs Python 2)

[Ian Cordasco]

On a related note, I've been intrigued by Haskell's idea of currying
all functions, and have an implementation that works for pure
functions but not for callable classes or methods over on
https://github.com/sigmavirus24/curryer.
