Yes it is useful.
And I think I have found a way to support them within the
is(T S == super) would become
auto f(alias T)
static literal bool r = is(T S == super);
// here alias S = (r ? SuperTupleOf(T) : ErrorType) is
// where ErrorType is the value for which `!is(ErrorType)` is
still the pattern matching part is going to be a pain to
Without the some limitations we have right now.
