Sorry, something went wrong.
Now that the default parser is the new PEG parser, ast.parse uses it, which means that we don't actually test something in test_peg_parser. This PR introduces a new kwarg `oldparser` for `_peg_parser.parse_string` for specifying that a string needs to be parsed with the old parser. This kwarg is used in the tests to actually compare the ASTs the new parser generates with those generated by the old parser. Closes we-like-parsers/cpyhton#93.
