I think we should not touch these.  First it doesn't buy us much as we
are using the old parse/print functions for the visitor-based access,
which doesn't look like a good idea to me.  Also they will not stay but
will be converted to child<> and link<>, so I think it is better to keep
the old stuff in the legacy<> namespace.

Agree on the bit/bool/int types.  Although we maybe should apply some
care to integer bus properties, some of them are used for addressing and
will most likely replaced by child<> and link<> too.

cheers,
  Gerd
