That you needed to explain that is kind of funny in light of your claim that
this is somehow clearer.  <wink>  I agree with skipping the temp variable in
favor of just doing an immediate return True/False in the appropriate
branch, but what's with the OCD (obsessive compulsive disorder) re:
collapsing lines?  This ain't Perl golf, you know.
