I suppose that I am willing to lessen my expectations from _all_ to most.
;-) Regarding your example I could also do:

    if something():
        def nothing(): return 0
    else:
        def nothing(): return 1

But this doesn't stop IDEs from attempting to do auto-completion.  I'm not
trying to find hidden exceptions... just trying to easily get an idea of
what could go wrong on each line of code.
