OK, then let's reformulate my question: Why do we have a non-H98 ReadP at all?
If I see it correctly, it is only to save one type parameter, but this looks
like a bad trade-off. We could deprecate the current non-H98 ReadP then (keeping
it for backwards compatibility) and offer a new pure H98 version. This would
avoid the current #ifdef horror and keep the interfaces compiler-independent,
both are worthy goals IMHO...
