Added virtual members to class metadata 

There does not seem to be tests for any of the metadata at present; they are
implicitly tested through various implementations that make use of them.
This will also be the case here ("will"---in coming commits), but needs to
change.

The upcoming reflection implementation would be an excellent time to do so.
