    Methods inParensOrError and similar take a second argument which, should the next token not be the expected opener (e.g. LPAREN) will be returned instead of the contents of the groupers. However in all cases accept(LPAREN) will be called, so a parse error will still result. If the grouping is optional, in.token should be tested before calling these methods.

    Skip trailing comma is pushed down to scanner because this abstract parser doesn't have token info.
