template Select(bool condition, alias T, alias F) { static if (condition) alias T Select; else alias F Select; } template Select(bool condition, T, F) { static if (condition) alias T Select; else alias F Select; } unittest { static assert(is(Select!(true, int, long) == int)); static assert(is(Select!(false, int, long) == long)); static assert(Select!(true, 1, 5) == 1); static assert(Select!(false, 42, 23) == 23); }

Seems to be fixed, it works for me using 2.053 (I have tested with -unittest).
