Hi,
I propose to create an issue for old pull requests and close them with
some kind words and encourage the author to reopen it if he or she
starts working on it again.
Proposal for policy: our PR queue should be for active work. If PR is
not ready to merge and nobody is working on it, we
Our code printers support only a narrow set of SymPy. More advanced
mathematical operations like `Gamma` go completely unsupported and even
give wrong results.
This is easy to fix. Find a SymPy operator, figure out how to print it in
C, and make a commit. Here is an example with the Gamma
I've gone ahead and closed over half of my pull requests. I suspect that
the more prolific contributors should be able to do a lot of this work on
their own PRs very quickly.

Thanks again for raising these issues. This is the status as I see it

Hi, I came across this while working on the lie group methods, Is this a
bug or am I missing something quite obvious?
r, x = Symbols(r x)
eq = Integral(1/sqrt(a0 + a1*x + a2*x**2 + a3*x**3 + a4*x**4), x)
eq = eq.subs(x, r)
print(eq.doit())
x/sqrt(a0 + a1*r + a2*r**2 + a3*r**3 + a4*r**4)

Hey Matt et al.,
Between the responses (and code updates) from Fred, Jason and yourself, all
of my present questions have been answered. Now I just need to get more
familiar with Theano. I was quick to assume that I would understand all of
the printer code, but at least now it is all beginning
