hmmm ... this is clever to restrict what is a signal and what is not.
I like the class inheritance better in this case, as it is easier and
one less feature to learn for average hardware engineers. I do
completely understand why software engineer likes this approach, you
just add one line and the class behavior can be modified without
needing to modify anything of the class itself, especially when it
already has a non-empty inheritance list.
