This is an initial implementation of Effect.Aff that copies the JavaScript implementation more or less verbatim.

There is still much to do:

• general bug fixing, as there are some subtle bugs due to copy and paste errors
• making the code more pythonic
• correctly guarding code with threading.Lock

The repo is in alpha development. The code is not fit for anything other than experimental usage. It needs additional development and testing before being able to be incorporated into the official package-set for purescript.python.
