Prothon should not borrow Python strings!

Wow, thanks, this is some really great stuff.  I'm going to have to go
off and study up on it.

This may be a stupid question, but couldn't I have many "types" of
strings and some be 8-bits, some 16-bits, and some 32-bits?  Couldn't
normal method overloading handle the type conversion?  Why is there all
this confusion?  Isn't this what object-centric computing is designed
for?
