Boost PP doesnt compromise type safety...

Agreed, but we can and do approximate them with prefixes...

We can have polymorphism if we want, see my post sometime ago:
http://lists.boost.org/MailArchives/boost/msg79530.php.  We do use this
technique in our BOOST_TYPEOF proposal.

Things change.  New techniques get discovered.  What used to be "ugly
macros" now becomes quite elegant and _very_ useful mechanism, that can be
used to achieve things that otherwise ***just cannot be achieved***, and
_especially_ if you use macros in the library interface.  Why should we
throw this away?
