Yep, I see. Unbounded methods would require changes to the Ruby core, right?

Well, my posted implementation for InstanceMethod separates the concept of
method from the receiver. You just hold reference to instanceMethod and
'.call' it when needed. But in not so abstract level it has to maintain the
reference to the instance of course.

But aren't Proc objects quite close to the unbounded methods. Now, if only
they'd work like methods (multiple returns, same kind of argument passing,
associated iterator handling) and you could choose should they bind anything
from the context when created.
