Comment(by nbruin):
Solve it how you like. I don't particularly mind what sage does. I've
given you the reasons why __I__ won't be doing it. I think you can settle
on some fixed example expression inside the error message, a la "A
declaration along the lines of assume(x>0) may help solve your problem.",
because the surgery that is currently done doesn't always lead to useful
suggestions anyway, i.e.,
{{{
sage: var('x,y')
sage: integrate(log(x^2+y^2),x,0,1)
}}}
suggests {{{assume( (y+1)*(y-1) > 0 )}}} which doesn't make the question
go away, and the fact that sage clearly goes out of its way to make a
suggestion that doesn't turn out to help really does look silly.
Let's keep this issue outside the ticket comments, because they are
getting too long to scroll already.
