Even this fails:

Is Tuple only meant to store types or named types?
std.typecons.Tuple is a value type, mostly like those tuples you find in
other languages like Python, Haskell, etc.
What you are likely looking for is std.typetuple.Typetuple.
If you read that page he is referring to, it seems like you should be able
to create an expression tuple.
I don't know if that works with std.typecons.tuple.
In fact, I don't think I've ever seen some of the stuff that's in that
page, especially the mixed type+expression tuple. Is it valid?
