I see. In fact, there's no way this would work like builtin tuple because
tuple() only accepts a single argument. I'm +1 on your suggestion.

Not only that, but there would be an inconsistency for nested Tuples:
Tuple((1, 2, 3)) (i.e., Tuple(tuple([1, 2, 3])))
Tuple(1, 2, 3)

Another point I just noticed is that sympify(tuple()) - tuple(), not a
Tuple. So this is happening (in my branch):

This is looking good. I've now added checksol to check solutions and
have added a fallback mechanism to throw away denominators. This is
going to solve a bunch of problems.

Hi,
apparently it is possible to use a JSON api [1] to Wolfram|Alpha with
2000 noncommercial calls per month. I think we could integrate it into
sympy, with having each user specify his own Wolfram ID.
This is kind of similar to the oeis() function (issue 2203). Maybe we should
create a module for these kinds of things. It should to in utilities.
