    Parse a sequence of field declarations, separated by commas.

    Parse a sequence of field declarations, separated by commas. This one is tricky because a comma might also appear in an initializer. Since we don't parse initializers we don't know what the comma signifies. We solve this with a second list buffer `maybe` which contains potential variable definitions. Once we have reached the end of the statement, we know whether these potential definitions are real or not.

    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.
