Re: for -- else: what was the motivation?

Got it, thanks! Actually the reason I never used "else" was the violation of the rule of beauty "shortest block first". With if--else you can easily follow this rule by inverting "if" expression, but with for--else you can't. The loop body of the simplest example is already three lines, in
