Diggory:
I'm sorry that you don't like it, but I don't see why it's any more of a hack than any of the other methods presented thus far?
t{} doesn't look wonderful compared to Python-like tuples, but maybe it's the best syntax seen so far that doesn't clashes with tuple(), Tuple!(), TypeTuple!(), comma operator syntax, lambdas, parameter-less lambdas, and so on.
