In this case map!() can't be applied on a iota():
import std.algorithm: map;
import std.range: iota;
void main() {
const step = 2;
iota(0, 10, step).map!(i => i);
}
DMD 2.063beta5 gives:
...\dmd2\src\phobos\std\algorithm.d(482): Error: cannot modify struct
result._input Result with immutable members
...\dmd2\src\phobos\std\algorithm.d(390): Error: template instance
test.main.MapResult!(__lambda2, Result) error instantiating
test.d(5): instantiated from here: map!(Result)
test.d(5): Error: template instance test.main.map!(__lambda2).map!(Result)
error instantiating
