It's also buggy. A more useful version would be:
template isBaseOf(BASE, C) {
enum isBaseOf = {
static if (is(C S == super))
foreach (A; S)
static if (isBaseOf!(BASE, A))
return true;
return is(C==BASE);
}();
}
Sorry, didn't test this properly; going to blame the dlang is-expression docs.
It's not like D has multiple inheritance, so using "base classes" (plural)
is very misleading...
