It doesn't have all sources. It could load a library. That can never be

Currently, a virtual call is done with:
(*vtbl[i])(args...)
It makes me wonder if the following would be faster:
method_fp = vtbl[i];
if (method_fp == &method)
method(args...)
else
(*method_fp)(args...)
Anyone care to dummy this up and run a benchmark?
It's also possible to, for the per-class static data, have a flag that says
"isfinal", which is set to false at runtime whenever a new is done for a derived
class. Then, the method test above becomes:
if (isfinal)
