Not unless the compiler could read your mind!
The syntax looks fine it's the semantics that are suspect. Wrong is a 
word that I try not to use as it tends to upset people, let's call them 
"differently right" ;-)

BTW having more than one return statement in a block is a little thing I 
know but it drives me nuts ... another "Pythonic" thing I'll have to get 
used to I suppose.
