Great. Like I said, you'll probably want to use judicious calls to

This ended up being a bit of a marathon repair, but such expressions work
nicely (and quickly). A big thanks to @tsndiffopera who got this going,

New issue 3223 by asmeu...@gmail.com: degree((x+1)**1) takes too long
http://code.google.com/p/sympy/issues/detail?id=3223
degree() should be able to return almost instantly, but something like
degree((x+1)**1)

http://code.google.com/p/sympy/issues/detail?id=3223
as_leading_term is your workhorse:
eq=(x+1)**1
eq.as_leading_term(x)
1
eq.subs(x,1/x).as_leading_term(x).subs(x, 1/x)
x**1
Comment #2 on issue 3223 by smi...@gmail.com: degree((x+1)**1) takes

http://code.google.com/p/sympy/issues/detail?id=3223
But watch out if it's not a polynomial:
-(exp(x)).subs(x, 1/x).leadterm(x)[0]

http://code.google.com/p/sympy/issues/detail?id=3224
Is there any benefit to reasoning about generating functions (moment,
cumulant, etc...)
