Hi!
A feature I use surprisingly often in Python is the else clause on
loops. Is there something similar in D? Basically, the idea is that
your loop is "looking for something" (or some condition), and that
you'll break out of it if you find what you're looking for. If no break
occurs, the else clause is executed.
It makes for quite clean code in many cases, IMO. The alternative can
be a flag variable, I guess, or a goto-statement (to right after the
"else" bit) instead of a break. Or put it in a function, and use a
return instead of a break ... or use scope() somehow, perhaps.
I see that the feature has been requested a few years ago [1], so there
might not be that much demand for this sort of thing. Is there perhaps
a D idiom here already?
