This is _not_ what I said.

Quoting from my earlier post:

"""
>    return? expr

This syntax does not fit well within python ideology.

>    if _temp: return _temp

This could be simplified to just:

return expr or None
"""

Please read carefully before putting words in my mouth.

I stated very clear y that return? expr didn't seem fitting
in the python ideology as syntax for this behavior.

cheers
