I agree that "return x++;" is not too bad for a human reader, but code with
mutation inside expressions (mostly written by other people) has caused me tons
of troubles (and the semantics of ++ and -- are as much undefined in D as in C,
still). So I usually kit it with fire as soon as I see it.
I'd like to modify the -- and ++ to make them return void. I think Go is
designed like that.

Only if you don't care a lot for the performance of that specific loop. (DMD is
sometimes not even able to optimize foreach() loops as well as for() loops. Go
figure what it does on iota()).
