Bug description
Parsing invalid patterns inside well-balanced parentheses produces an error message saying that parens don't match.
I provide a patch that fixes the problem by adding a few more error rules in the parser and relevant error messages.
Steps to reproduce
$ echo 'match x with (1 as ) -> 0;;' > /tmp/a.ml
$ ocamlc /tmp/a.ml -o /tmp/a
File "/tmp/a.ml", line 1, characters 19-20:
Error: Syntax error: ')' expected
File "/tmp/a.ml", line 1, characters 13-14:
Error: This '(' might be unmatched
Additional information
After applying the patch, the new error message is
