A wider benchmark:


import std.typetuple: TypeTuple;
import std.range: iota;
void main() {
    foreach (T; TypeTuple!(byte, ubyte, short, ushort,
                           int, uint, long, ulong))
        foreach (i; 0 .. cast(T)10)
            pragma(msg, T, "  ", typeof(i));
    pragma(msg, "");
    foreach (T; TypeTuple!(byte, ubyte, short, ushort,
                           int, uint, long, ulong))
        foreach (i; iota(0, cast(T)10))
            pragma(msg, T, "  ", typeof(i));
}


byte  int
ubyte  int
short  int
ushort  int
int  int
uint  uint
long  long
ulong  ulong

byte  int
ubyte  int
short  int
ushort  int
int  int
uint  uint
long  long
ulong  ulong
