I would guess that there is not going to be a big interface change before
the next release. At least nobody is working on it as far as I know. And
much of the "mess" will be ironed out "inside", I would think, so even when
it all works better there shouldn't be a huge change. Eventually we want a
different way to represent solutions. If you are writing a book you might
consider using the "dict=True" or "set=True" option to get a consisitent
output:
>>> solve((x-y-3,x+y-7),set=True)
([x, y], set([(5, 2)]))
>>> solve(x-3,set=True)
([x], set([(3,)]))
>>> solve((x-y-3,x+y-7),dict=True)
[{x: 5, y: 2}]
>>> solve(x-3,dict=True)
[{x: 3}]
>>> solve(x**2-3,dict=True)
[{x: -sqrt(3)}, {x: sqrt(3)}]
