Places a TypeTuple can be used

[Ali Çehreli]

I know of three places a TypeTuple can be used at:

1) Function parameter list

2) Template parameter list

3) Array literal element list

Are there more?

import std.typetuple;

void foo(int, string, double)
{}

struct S(T, float f)
{}

void main()
{
     // 1) Function parameter list: May not contain types
     foo(TypeTuple!(42, "hello", 1.5));

     // 2) Template parameter list: May contain types
     auto s = S!(TypeTuple!(char, 2.5))();

     // 3) Array elements: Elements must be the same type
     auto a = [ TypeTuple!(1, 2, 3, 4) ];

     // Are there other places that a TypeTuple can be used?
}
