    3838* Make sure that PMC_data is only used for the PMC-specific attributes struct.

     40* Watch out for MULTI functions in base classes.  This is mainly a concern when working on an extending PMC where the base PMC has a MULTI function that the extending PMC doesn't override.  For example, the String PMC needs its own is_equal MULTI, since scalar's is_equal MULTI assumes that any extending PMCs use the UnionVal rather than ATTRs.
