I don't think you can have it both ways. You can pass a member name
in the form of a pointer to member function. But if you spell it
out in your code and it doesn't exist, you will get a compile error.
Or, you can specify it in a SFINAE expression without the compile
error but you have to spell it out. Perhaps you can use the first
approach for the implementation and the second as a thin wrapper
over it (maybe with some macros to shorten things up even more).
