Well... Having had to recent pleasure to find code like this:

   bool foo::check(T *obj) const
     std::string name = obj->name();
     bool value = (name == "foo");
     value = value || (name == "bar");
     value = value || (name == "foobar");
     value = value || (name == "zoinc");
     value = value || (name == "barfy");
     value = value || (name == "zoobie");
     value = value || (name == "ayeyei");
     return value;

That was one of the contributors to ~800'000 memory allocation calls
per second. It was called... often.

I'd say there's something a bit more fundamental going on here than
_just_ a library design issue :-) No class can be all things to all
