My suggestion is very simple.
1. Change all words "built-in tuple" in the documentation to
"built-in
sequence". Then, in the D language world, we can have clarify
name for
the built-in one.
2. Introduce new templates, Seq, TypeSeq, and ExpSeq.
template Seq(T...) { alias T Seq; } // identical with
std.typetuple.TypeTuple
template TypeSeq(T...) if (allSatisfy!(isType, T)) { alias
T TypeSeq; }
template ExpSeq(T...) if (allSatisfy!(isExpression, T)) {
alias T ExpSeq; }
If you really want to a sequence with heterogeneous
elements, use
Seq template. Otherwise use TypeSeq or ExpSeq based on your
purpose.

(This is also what would be in my never finished std.meta
proposal – interesting how we seem to converge towards the same
solutions in the metaprogramming space…)
