Could you be more specific about what you think these guys don't understand? To a non-python expert type there isn't much difference between the article and the wiki information. I was very impressed at the goals as spelled out on the wiki and they seem to have a decent roadmap up. Is it the

Could you be more specific about what you think these guys don't understand? Were you asking me or William? My impression from reading through the wiki is that these guys *do* know what they're doing, contrary to what William seemed to think, though I suspect neither of us has actually read

Thanks, that does answer my questions. I'm not an expert, but I did find the possibility of speeding up python this much was an interesting one. Let's hope they'll succeed, though I guess it may take them years. I hope they are in it for the long run. Bill. On 28 Mar, 01:45, Carl Witty
