  Historical note: JavaParsers started life as a direct copy of Parsers but at a time when that Parsers had been replaced by a different one. Later it was dropped and the original Parsers reinstated, leaving us with massive duplication between Parsers and JavaParsers.

  This trait and the similar one for Scanners/JavaScanners represents the beginnings of a campaign against this latest incursion by Cutty McPastington and his army of very similar soldiers.

#### abstract class ParserCommon extends AnyRef

This is now an abstract class, only to work around the optimizer: methods in traits are never inlined.

    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.
