lambda and nested functions

[wjaskowski]

Do you see any possibilities to allow lambda or nested functions with parmap.map?

Not really. Unfortunately lambda functions are not pickable, so they are not suitable for multiprocessing.

There are some workarounds, see for instance: https://stackoverflow.com/questions/4827432/how-to-let-pool-map-take-a-lambda-function

I'll close this because I can't fix it, but feel free to comment if you have doubts.

What about using https://github.com/pya/pickablelambda under the hood?

Looks good! I don't have much free time right now to implement this. Feel free to submit a pull request if you want, otherwise I will do the work eventually 👍
