How is (1, 2) different from [1, 2] (static array)? It makes no
sense to me to have both and probably a bunch of conversion
rules/functions.
Why don't you consider extending (type-homogeneous) static arrays
to (finite type enumerated) tuples? It solves
- 1-tuples
- comma operator vs. tuple literal
instantly.
You'd have T[n] as an alias for the tuple type consisting of n
objects of type T.
I've written something about that here:

(sorry for my bad English in that post)
The main reason I'd vote against the DIP: Parenthesis should only
be used for operator precedence and function calls.
