I can't think of many example situations where I would have parenthesis 
on a return statement.  If the expression involved was too complicated 
to be clearly understood, I'd break it up.  A quick search of some code 
I've written shows occasional use of it - often for something like:

	return (x == 0);

I haven't bothered looking at the context, but I assume I simply thought 
it looked clearer that way.
