Bart, we get it: you don't like the trade-offs that Python has made.
You want Python to be faster, but it can't be because of dynamic features
that you don't think are worthwhile.  That's fine, you don't have to
use or like Python.

You want Python to have features other languages have, like a switch
statement. It doesn't have it, sorry. Not all languages have the same
features. If they did, we'd only have one language.

Again: you don't have to like Python.  But going on and on here about 
your vision of how Python could change is not productive.  We aren't
going to agree with you that Python's dynamic nature is a bad trade-off,
and even if we did, Python is not going to change in the way that you
want.

You basically said, "I don't want to use Python the way it was designed
to be used." It's no wonder you are not pleased with the results.

You can choose any language you want.  You can even implement your own
language, as you have.

You don't like Python.  Can we leave it at that?
