[Python-ideas] an unless statement would occasionally be useful

[Charles Hixson]

I'm envisioning "unless" as a synonym for "if not(...):"  currently I use

if .... :
     pass
else:
   ...

which works.

N.B.:  This isn't extremely important as there are already two ways to 
accomplish the same purpose, but it would be useful, seems easy to 
implement, and is already used by many other languages.  The advantage 
is that when the condition is long it simplifies understanding.
