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.
