Comment (by eviatarbach):
I was just going to work on this today!
I haven't tested the code, but looks good. Just a few things:
1. Is there any reason why you're converting the variables to their string
representations in `._variables()`?
2. The parameter in `Expression.gradient` is called `variables`; I think
it would be good to switch `vars` to `variables` for consistency.
3. I think there should be test(s) for `.curl()` with the variables
parameter.
4. I believe the `raise TypeError, "curl only defined for 3 dimensions"`
syntax is deprecated, and that the string should be passed as an argument.
