[Python-ideas] documentation: mention the version in which a syntax construct was added

[Mathias Panzenböck]

I wonder in which version the "except Foo as e" syntax was added (as opposed to "except Foo, e"). 
The documentations does not state this but I think it wasn't there in Python 2.4.

I propose that such things are always mentioned in the documentation and formated so that you can 
easily find the version numbers.

See how Mozilla marks such things (scroll down):
