Just to clarify this

    a) it really was meant for exceptions not as yet 
       another way to spell "if"

    b) it wasn't a proposal just an idea

So the 'except' idea is that you can say

    result = obj.method() except AttributeError: None

which eases use of "do it and handle exceptions" instead
of look-before-you-leap.  And it's easier to read 

1) there are only two entities involved 

2) it's obvious what is the "normal" case and is easily
   spotted what the value is in case of an exception.

But as with PEP308 it has bad implications on readability
when used inside non-assignments.  So i am -1 on my own
non-PEP.
