If you specifically want to iterate over it, then I think that you need to repeatedly call popFront (or callPopFrontN if it hasLength). However, if what you want is for the resultant range to be empty, you can use std.range.takeNone. If it can, it'll return the same range type as the original, and if it can't, it'll return takeExactly(range, 0). - Jonathan M Davis
