I think rather than checking to see if the function has been assigned, it would be cleaner to initialise this property in the constructor with (a, b) => a === b , then you don't need this check.

I haven't fully tested yet because I'm not quite sure that this is going in the right direction. If it seems to be correct, I'll update and add maybe an example.
