Please no special cases.

You misunderstand, what I mean is that the comma should be *part of* for-loop syntax, instead of being part of expression syntax. I.e., for-loop grammar should read something like this:

for-loop:
        "for" "(" loop-init ";" loop-condition ";" loop-increment ")" block

loop-init:
        comma-separated-exprs

loop-condition:
        comma-separated-exprs

loop-increment:
        comma-separated-exprs

comma-separated-exprs:
        expression
        expression "," comma-separated-exprs

And the grammar for expression should have zero references to comma operators.

loopinit is a statement, but I see the idea. Works for me.
