That works well, but what about when the expression is multivariate,
such as:
expand((1+x+1/y)^10)
It would be nice to have a general command to count the number of
summands in such an expression.
Yep, I agree. Here is a *terrible* way to do it:
sage: var('x,y')
(x, y)
sage: f = x+y + 1

You can use AppleScript to create a launcher for Sage:

No, the format for multiple edges in a dict of dicts is {u : {v :

My bad, I misread your complaint. That's definitely a bug.
