override def ch: Char

The library and compiler parsers had the interesting distinction of different behavior for nextch (a function for which there are a total of two plausible behaviors, so we know the design space was fully explored.) One of them returned the value of nextch before the increment and one of them the new value. So to unify code we have to at least temporarily abstract over the nextchs.
