1. I think removing comma operator does not have useful effect

1a. If you want to use parenthesis syntax (...) for tuple,

resolve one-element tuple ambiguity first.
(exp) // one-element tuple, or just an expression ?
And, removing comma operator does not resolve this issue.
I believe this is a non-issue. From a language-users POV, there
should be no difference between a one-element tuple and an
expression, thus there's no need to distinguish the two. (The
actual implementation in the compiler may of course treat them
differently.)
Or, if you really want to distinguish them, this would work:
(1,2) two-element tuple
(1,) one-element tuple
(1) simple expression
(,) empty tuple
