Hi Steven,
I too am just learning about metaclasses in Python and I found the
example you posted to be excellent.
I played around with it and noticed that the issue seems to be the
double-underscore in front of the fields (cls.__fields = {}). If you

Just as feedback, I went back to the __init__ style routine, weeded
out a few things, installed python 2.6.1, and it works great. Thanks
for all your help. Now I've got to convince 1000 people at my company
to switch. That's going to be the tough part.

If I cast it long then it prints fine, but I was hoping there would be
a slicker way (to accomplish this in the class itself).

It seems like there's no way to do what I'm trying. I am confined to
Python 2.5.3 for business reasons.
So I want a class ShadowRegister, which just has a value that I can do

It needs to read HW reg and adjust ChipRegister value, or
ShadowRegister and change the HW value (order was reversed). I will
look at MyHDL again though to see if there is some reason it can print

Hi,
I'm making a project into my first package, mainly for organization, but
also to learn how to do it. I have a number of data files, both
experimental results and PNG files. My project is organized as a root
directory, with two subdirectories, src and data, and directory trees
below them.
