[docs] [issue25435] Wrong function calls and referring to not removed concepts in descriptor HowTo (documentation)

[Martin Panter]

Martin Panter added the comment:

Thanks for the patch. I left a few comments on the code review. I think the class is meant to represent a real function object, not a wrapper. And it would be good to update the following paragraphs about unbound methods.

Also, it looks like the rest of that page could do with some other updates. E.g. no need for explicit Function(object) base class, no need to mention that a method exists in Python 2.3, code could use @classmethod decorator syntax. But these are a slightly separate issues.
