I think what you have found is a remarkable characteristic of this
language. Somehow, perhaps something to do with guido or python
itself, python has a very strong non-dogmatic streak. It's a relief
really. If I were to pose a "is python or its community really xyz?"

yes I was wondering what "x=x+1" meant until you translated it... oh,
"x = x + 1" of course! I thought to myself.

what you have is a totally acceptable factory system. Not sure why
you are using a generator, but that's another matter.
I agree with the previous replies regarding inheritance... this is not
a case for inheritance. You could, however, have Bar be a borg with

I go around and around on this issue, and have ended up considering

likely that user is a programmer. I don't really think there is a

I'm not the OP and I may be biased by C++, I can imagine the

I've just come to the conclusion it's not possible to call functions
in python, to do so is undefined and indeterminate, like dividing by
zero. Henceforth no calling functions for me as clearly it's the
devil's playground.

we have software we are putting into package form. So far, all the
code was in local py files and we imported between the modules as

how import affects the importing module.

coming to being causa sui. Having to actually implement a language is
disgusting and unnatural.

It is clear to me that Python is a multiparadigmed object oriented
language. It is clearly possible to write procedural code... that is,
Python does not force object oriented syntax or concepts on you and
insist you define everything in such a structure. Is the OO it allows
