How can you even say this, when the manual has a section about
object-oriented modeling, which has a Queue class, which you have
just been struggling with?

Perhaps this stuff really is too hard for the "general python
developer", though I still don't understand why.

One more attempt: MyHDL, the modeling language, is very general:
as long as you feed it a number of generators communicating
through signals, it is happy. It doesn't matter whether these
are created by functions, classes, subclasses, mixin classes,
multiple inheritance, whatever. MyHDL is therefore what you
want it to be - functional, applicative, procedural, object-oriented,
aspect oriented, whatever.

It is only when you need conversion that restrictions drop in,
but identifying MyHDL with conversion or synthesis restrictions
is a sign of basic misunderstanding.

I understand that this may not have been clear enough in the
past: but this should be fixed now with the What MyHDL is not page,
and when I separate synthesizable/non-synthesizable chapters
in the manual.

Coupling a sensitivity list to a module makes no sense.
