AUIU, foreach has both of these forms:foreach(x; 0..5) foreach(x; someRange) Also, we have: auto someRange = iota(0, 5); Little idea: How about this genralized lowering? 0..5 // iota says "Gimme some sugar, baby." // and thus it is lowered to -> iota(0, 5) Of course, if that hinders optimization for foreach(x; 0..5), then the compiler could just "optimize" that particular case by not bothering with the lowering and doing as it currently does. But the benefit is things like this: // Stealing Andrei's "filter even" example: filter!`a % 2 == 0`(iota(1, 5)) // Give iota some sugar, baby: filter!`a % 2 == 0`(1..5) I suppose the obnoxious float-literal definition could get in the way, but when is it ever legal syntax in D to have two numeric literals next to each other? (And foreach seems ok with it anyway) Pardon if this has already been suggested.
PS: your proposal would also logically allow, I guess, expressions like (n in min..max). Would love it.
