Now, see, that's the thing. The more ways there are to write the same 
program, the harder any given program will be to understand.

This is indeed a fairly deliberate approach in the Python world, and

I think Fredrik was trying to make a point about the need to be accurate 
in discussing language features, but I could be wrong.
