I switched to python some years ago because:
   - it is used by mainstream open source ai research and many hobbyists
   - it has language support to reference, mutate, and recompile its own
   bytecode while executing it, and has some syntax mutability
   - it's concise
   There are downsides to python. Notably it is hard to debug interpreter
   problems from chip or kernel misbehavior. C is much better in my
   opinion.
   Anyway, I've been using python for some time without understanding
   __new__, which is an important construct.
   Here's how the manual says __new__ works. It's not complicated.
   1. python calls Class.__new__(cls, ...) when Class(...) is called.
   2. Unlike all other methods, __new__ is never passed a self object, and
   always passed a class object, no matter how it is decorated.
   3. The return value of __new__ is passed on to __init__, after __new__
   returns, if and only if it is an object of the class. Then it is
   returned to the user.
   4. New objects can be constructed via super().__new__(cls), to return.
   This lets one write constructors that for example instantiate a child
   class selected from arguments and perform other tricks.
