Can you help me learnHaskell?

My OOP mind struggles every time I attempt to learn it 😢

I am a Software Engineer who mostly works withPython but used to work withC/C++ andJava a long time ago.Hope one day I will be able to understandHaskell (I have a dream to learn functional programming).

PEP 505 None-aware operators is a feature that I miss the most inPython.

I?.really?.want?.this?.feature??"Or not?"

If you are usingFastAPI and use function return type annotation asresponse_model you should know -I am the one who implemented it 😄(FastAPI #1436).

Also, I have createdfastapi-paginationpackage that helps you to paginate things (obviously) usingFastAPI 📖.Another thing that I currently work on isfastapi-filters package.Hope one day it will be useful for someone asfastapi-pagination is 🍸.

I have several contributions toPython itself (commits).The most interesting one is(#23316 Store func annotations as a tuple).This optimization reduces memory footprint and improves performance of loading modules having many func annotations.

>>>sys.getsizeof({"a":"int","b":"int","return":"int"})232>>>sys.getsizeof(("a","int","b","int","return","int"))88

The tuple is converted intodict on the fly whenfunc.__annotations__ is accessed first.

I have created a plugin (pycharm-evaluate-async-code)for PyCharm that helps you evaluate async code the usingEvaluate Expression window.This is really useful when you are debugging your code and want to check some async stuff.I guess it's my favorite project that I have ever done (because I used it every day and it really saved me a lot of time).
