And here we go again. Sorry for posting unfinished stuff:

I don't know why this needs special syntax anyway. Maybe, somebody could 
explain. Even Guido said it was just for procrastinating. So, I don't 
give much weight to it.

Anyway, what's the difference between:

a = <something>


def a = <something>


Both evaluate RHS and assign the result to a name (if not already 
defined, define the name)

The only benefit I can see is some a syntax like:

def a

which defines a name in the scope without content. If that's useful? Maybe.
