Re: [myhdl-list] Feedback request on decorators in MyHDL

[Haitao Z. <ha...@gm...>]

Jan,

I remeber reading an interesting thread on decorators in
comp.lang.python. Some consider the decorator feature a hack on the
polymorphic function, because it can not replace true polymorphism
which is hard. So there is question whether this feature should stay
with future Pythons. A main issue is that there were no truely good
examples of usage pattern (polymorphic dispatch usage does not
simplify the user interface since python function already supports
arbitrary argument types) and often the dispatch through decorator is
more confusing than explicit control statements. However I think your
usage pattern in myhdl holds as a true example of how it can be used
to the advantage on the user side. I don't think decorator will go
away and this myhdl usage pattern strongly supports keeping
decorators. It will be nice to make it more well known to the Python
community.

Very nice and pythonic discovery indeed.
