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.

I've been wrestling with this a few days and can't quite figure out
whats wrong.
I'm trying to install Google Protocol Buffers in sage-3.4 which used

Could you be more specific about what you think these guys don't

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.

There has been recent work on the Lambert W function

function can take advantage of that yet. If you are

Hi Golam,
Thanks a lot for looking into this. It would be great if you could fix
this along the way when you solve your original problem.

Hi,
There seems to be a quite strange behaviour of _richcmp in
structure.element.pyx. If the parents need to be coerced, afterwards
left._richcmp_ is called. But if they don't, left.__cmp__ is called,
hence
assuming a totally ordered parent. I don't see any reason for such a
behaviour and it rend
This is indeed a very interesting idea. Luckily something like this
already exists, except that it is not using the whole of Sage but only
Maxima. Take a look at stack.bham.ac.uk.
