typeid() is a runtime function. I think it will be costly every time
toHash is called. The function pointer can be initialized once.

The getHash() member function of the particular Typ
I have a class which contains an int[] and some other stuff. I want to

int[] is the only part which should produce the hash code. I know that
int[].toHash() is defined somehow, because I can put int[] directly into
an AA
