Python promises (Python 3 version)
A Python implementation of the promise pattern for asynchronous programming.
This is a special implementation of promises in that it can be used both for "promise of a value" and lazy evaluation. The biggest upside for this is that everything in a promise can also be a promise, e.g. filters, callbacks and errbacks can all be promises.
This package contains the Python 3 version of the library.
