Yeah, this is what I tried to say by "different machine state";
compiling different behavior in the case of a special method
is an interesting idea. It is limited somewhat, since the
changed system state is not inherited to called functions.
But if __findattr__ performs its one, single task in its
body alone, we are fine.
