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
