What is the status of this? It's marked for the next release milestone, but
I don't think there's any progress.
As I understand it, we are considering renaming
Comment #4 on issue 3008 by vlada.pe...@gmail.com: Cython (apparently)
version causing problems
http://code.google.com/p/sympy/issues/detail?id=3008
Is there anything we should actually do about this? Are we even supporting
older versions of Cython? Is there any advantage to doing so?

We should figure out what version causes the problem and disable it (in
import_module).

I guess we never agreed on a better name to change it to.
I'm not sure this needs to be blocked on the release. It was originally
blocked on 0.7.0 because that was a

No, that's exactly the same bug.

Comment #1 on issue 3037 by ness...@gmail.com: integrate(exp(I*k*x)/(k**2 -
2*lamda + 1), (k, -oo, oo)) should be expressible in closed form
http://code.google.com/p/sympy/issues/detail?id=3037
This quite nicely illustrates a couple of problems with the code. First of
all, let us consider

By the way, I think lamda should be less than 1/2.

Unfortunately, right now, SymPy is unbearably slow in PyPy, so this

Hi all,
I am final year student doing Integrated M.Sc. in Applied Mathematics from
Indian Institute of Technology - Roorkee, India.
I love working in open source but my course curriculum gives very little
time or encouragement to do the same. I am planning to apply for PhD in USA

Also, note that @chainable does some magic :) Every operation returns
a new proxy, so I can store whatever I need. Currently I only store
the state (via closure) and a parent reference, but rather than
building state, I could just store (operation, [arguments]). There
are a few downsides
Great. Once we get it working, we should add it to setup.py test to
build the docs, and make sympy-bot return failed if they don't compile
without any errors. That's the only way we can avoid regressions.
