Self-modifying code! Yuck!
Nevertheless, try changing the line with new.instancemethod to this:
self.to_binary = types.MethodType(to_binary, self)
and see if it works. If it complains about the call to exec, then change
that part of the code to this:
ns = {}
exec(code, ns)
to_binary = ns['to_binary']
self.to_binary = types.MethodType(to_binary, self)
