Almost.

`Tuple` is defined at the top of the article as `template 
Tuple(E...) {alias Tuple = E;}`.

"TypeTuple" is later defined as a `Tuple` whose elements 
"elements are solely types".

So, in the context of the article, `Tuple!(int, long)` is a 
"TypeTuple", because it's a `Tuple` of types.

The article does not refer to `std.typecons.Tuple` or 
`std.typetuple.TypeTuple` at all. Specifically, the article's 
`Tuple` is not `std.typecons.Tuple`. And the article's 
"TypeTuple" is not `std.typetuple.TypeTuple`. However, going for 
bonus confusion points, the article's `Tuple` is defined the same 
as `std.typetuple.TypeTuple`.
