Note.  I did not mean to imply conditional return should be done
for performance reasons.

And I do not think the way this conditional return is done
serves better DWIMmery, which was my primary complaint.  So I
should probably have said "It's not for better DWIM, it is not
even for better performance, and I do not see a point".
