Daniel Murphy:
foreach_reverse(immutable i, 0...a.length)I know you feel that way, but I'd rather face the non-existent risk of accidentally mutating the induction variable than write immutable every time.
It's not non-existent :-) (And the right default for a modern language is to have immutable on default and mutable on request. If D doesn't have this quality, better to add immutable every damn time).
