But not necessarily the same bug. When one is fixed, let's be sure to check

Comment #11 on issue 3223 by gupta.ha...@gmail.com: degree((x+1)**1)

http://code.google.com/p/sympy/issues/detail?id=3223
Can you make it more clear. One thing I understood is that
-e.subs(x,1/x).leadterm(x)[1]
won't be useful when we are asking for the degree when we ask
Comment #5 on issue 3657 by mrock...@gmail.com: Summation over non-integers
http://code.google.com/p/sympy/issues/detail?id=3657
In an ideal case it would be able to handle any discrete set, not just
affine transforms of the naturals. For example it would be nice to be able
to sum over the

This can be done. I had misinterpreted the issue. I will get started with

This method will not work if f is non linear. For instance,
summation(f, (i, 0, 1, 0.2)) [0.2 is step]
= f(0.2) + f(0.4) + f(0.6) + f(0.8) + f(1.0)

Apparently one just needs to call series with the correct number of terms.

That would solve the particular example but not the general problem
X = Matrix(100, 100, lambda i,j: i+j)
Y = Matrix([1,5,13,29], :)

Comment #2 on issue 3655 by smi...@gmail.com: nan in compute_innermost
http://code.google.com/p/sympy/issues/detail?id=3655
That's a leftover, I believe, of making oo and Nan not be Rationals
(3a1f8c2dbe1ee31e6a38bde66fec9d1658f89e12). So now those values need to be
special cased.

might try test_numerically from randtest and the equals method:
