How can I generate a tuple of N type T's?

Question

I want to be able to write generate_tuple_type which would internally have a type alias type which would be std::tuple

Check the bottom of this link for an example:

http://en.cppreference.com/w/cpp/utility/integer_sequence.

You'll need to do a little more work to encapsulate the resulting tuple as a type alias, but the crucial construct here is std::integer_sequence and friends.
