I agree, which, IMO, requires a little bit of *ART*.
There are many concepts that need to pulled together and
succinctly explained.  I do not want set incorrect
expectations.

I don't know if I see a good way to explain that operator
overloading is appropriate for a sequence of instructions
but not for a hardware description (concurrent processes).
Or if it is absent if it will raise questions.

I don't if a plain "signal container" example would be a
better fit.
