In 3.3.alpha0, the following works fine:
sage: list= [[i,j] for i in [-3..3] for j in [-3..3]]
sage: [coords for coords in list if (coords[0])^2+(coords[1])^2-1==0]
[[-1, 0], [0, -1], [0, 1], [1, 0]]
The following doesn't terminate in a reasonable amount of time:
sage: f(x,y)=x^2+y^2-1
sage: li

I want to use MAXIMA to perform the separation of variables on a 3d nonlinear differential equation (and then solve a 1d equation). I think I can write a program to do this by trial and error with different functional forms, but I'm new to SAGE and don't want to start from scratch. Can you think

Just passing this thread on to sage-support, since it more properly
belongs there and some people there but not here might have
comments.
Also, is there any conceivable way that this sort of overloading could
somehow automatically make it into the definition of how interact
works, maybe via a key
the original was actually sqrt(2*x - 3) == 2 + sqrt(x+7) if that makes
a difference... hmmm

Hi
Is it possible to create a Ring over an arbitrary set in Sage? I have
a Python class and would like my instances to form a Ring.
I read somewhere that the built-in sage.rings.integer.Integer class
inherits from the Element class to allow it to form a Ring. Is there a
simpler example anywhere?
thank you Craig and William for your answers. Craig, I was using Sage 3.2,
