correct, but be aware that lots of dynamic objects seem to step outside 
the ABI by building shared objects with -Bsymbolic[1], or the equivalent 
visibility=hidden, or similar.  So now the typeinfo comparison operator 
is something like
   return this->name == other->name
   || (this->name[0] != '*' && other->name[0] != '*'
       && !strcmp (this->name, other->name))

nathan
[1] I see -Bsymbolic-functions is now a thing, which would be better
