Sure the "foreach" stuff is cumbersome, but the OP mentioned he is learning D, so it'd be best if he gets the properties of (dynamic) arrays and the foreach (which is nothing more than a simplification of common for loops).
IIRC it's also pretty much exactly what 'new' will do internally (except
it does it more generically). Do you always consider re-implementing the
standard library "simpler"?
