The iterator approach is clearly an abstraction and the call mechanism,
especially the argument binding, which would be interesting here, is
an implementation detail.

I don't think Signals are meant to support this kind of inter-slot
dependency. How about simply using a "reference to state" as argument
for the slots instead of trying to get the result used by value for
subsequent calls.
