That is actually a TypeTuple that does not auto-expand. May be 
even worth defining it as "alias Ungroup = TypeTuple!(Args)" to 
be more self-documenting at cost of some redundancy.

Also it does not need to be a struct, templates are not mandatory 
eponymous.

I think it is best solution for topic starter problem in terms of 
ROI and worth inclusion into Phobos.
