I will be actively promoting/developing it in the short term, but
in the longer term this will depend on the amount of user interest.
A good sign would be if people start complaining about performance,
because that would mean they are actually using it <wink>.  (The bad
news would be that someone, perhaps me, would then have to recode 
the package as an extension module in C.)

First on my list is to couple the package to a HDL simulator. My
goal is to be able to use Python's unit test framework on hardware
design written in an HDL - I believe Python would make a superior HVL.
Unfortunately, I don't have access to any commercial simulator right
now - only Icarus Verilog and I'm not sure that it supports the
Verilog PLI completely. I'm also not yet clear on how to do it best -
probably the best is to run MyHDL code in slave mode without
time queue (delta cycles only).

Definitely possible and interesting of course, but don't count on me for 
that one.

Well anticipated - it should indeed possible to generate HDL code from
an elaborated MyHDL description - this could be interesting for the 
synthesizable subset for example. I guess I would tackle Verilog
first - as a back-end format it is just fine <wink>.
