It was originally TypeTuple!(), and still is in druntime. (Yes, the PR 
recognizes TypeTuple, too, as it recognizes the pattern, not the identifier.) I 
don't know why it was changed to AliasSeq, which just grates on me as not 
indicating at all what it is. Probably Tuple would be the best name.

Not a bad idea. (.. is also used in case ranges)

I've also thought that more templates than AliasSeq might be suitable for 
compiler short-cutting.
