Not sure if enhancement request or bug, but filing as EH.

I think these should work:

//----
    auto a = TypeTuple!(int, int, int)(); //(0, 0, 0)
    auto b = TypeTuple!(int, int, int)(1); //(1, 1, 1)
    //auto c = TypeTuple!(int, int, int)(1, 2); //Should fail
    auto d = TypeTuple!(int, int, int)(1, 2, 3); //(1, 2, 3)
//----

Currently they all produce:
Error: function expected before (), not (int, int, int) of type (int, int, int)

In particular, I think this should work:
//----
    TypeTuple!(int, int, int) a = ...;
    TypeTuple!(int, int, int) b = TypeTuple!(int, int, int)(a);
//----
Though arguably, it's the exactly the same as the "d" case above.
