Maybe handle it instead with a parser flag that in certain contexts you
temporarily enable or disable?
Temporarily enable when parsing the [] expression and temporarily disable when
parsing an assignment expression?
Or instead hand inline cp_parser_expression into
cp_parser_postfix_open_square_expression and do the warning in the inlined
code?
Or add another defaulted argument to cp_parser_expression and only warn if that
argument is true and only pass true if called from
cp_parser_postfix_open_square_expression?
Or somehow merge the cast_p, decltype_p and this new warn_comma_p into a
bitmask (using enum?) and just pass one argument instead of 3?
