Sorry, this doesn't work. A "pointer to a member function" is _not_ a
"function pointer" and not a general (void*) pointer. It's size is
bigger than a pointer to a normal function because it stores
additional information about the object. I haven't found a conversion
between all "pointer to member functions" to something "comparable"
like a normal pointer or a number or a string. (Maybe typeinfo helps?
Is it portable?)

Take a look at this for the strange objects that member function pointers are:
