Without knowing the code much, this looks very much like any parser
you'd write: there is a pointer to the current char being parsed,
and this pointer has to be passed by reference so that it gets updated
in the caller !
So the "workaround" is correct, assuming you have a single thing to parse
and that parseRule will do it all.
