Unfortunately getName will cause an assertion fail for methods that has a
non-identifier name, such as destructors and overloaded operators.

Sure, in order to override the method the developer also needs to make the
method const in the child. But it is a common mistake to forget to add the
qualifiers. The purpose of the change is to find those cases. I think it is
more likely that the developer forgot to add the const qualifier than an
intentional hiding of a virtual method.
