That's a good idea.

Thanks guys, this is great stuff. You might want to memorialize this on a
wiki or something for newcomers to SymPy.
So a little bit about my background with Python: I'm a pretty experienced
Python programming, I understand operator overloading, I see your
@_sympifyit decorators all over the place
I know this has already been merged, but I wanted to say that this as
well as the other PR that was merged look extremely good. The test
coverage is fantastic and will give us a super-solid foundation to
build everything else on. Great work!

Well, you picked a particularly tricky example because it uses both
the main core and the polys.
So let's start with my_expresion (the core part). You already know
that x is defined to be a Symbol object (because you did this
yourself). You should also know that sin and cos are Function
objects,

Hey guys,
I'm reading through the SymPy code and, well, it's somewhat overwhelming if
you're new to the project because there's so much going on. (That's a good
thing too - it means its robust!)
Can someone help explain how this works?

>>> x = Symbol("x")

Hi.
Your expression is rather complicated, but as far as I can tell, you
did find a bug. Can you report it in our issue tracker
(http://code.google.com/p/sympy/issues/list)? Also, if you can find a
simpler expression that exhibits the same problem, that would help a
lot too.
By the way, you don
During some of the discussions from GSoC, we decided that reimplementing one of
the dozen of graph theory modules (including networkx) in SymPy would be a
waste of time.
However, if the graph theory were done in a symbolic way, so that it would
really require SymPy to be implemented, then I t

Hello!
I think I found a bug on collect. Can anyone tell me, please, if
either it is indeed a bug or I am doing something wrong?
Thanks a lot!

OK, I've finished it up. See https://github.com/sympy/sympy/pull/451.
Please review the changes to that branch, and also if you have the chance,
test it as you would the release candidate, as this should be the last fix
needed for the 0.7.0 release.
