Idx lets you specify a range of values. I think it is also handled
better by the code printers. If you don't need any of those features,
just using a Symbol should work fine.

Thanks Aaron,
That clarifies things a lot, but I think if you look at the
documentation, this isn't clear.
That leaves me with one question. Can this be used to index a sequence
of functions (as opposed to values) - think of the conventional notation
J_n for the n'th Bessel function, for example? This test suggests that
such a sequence can't be constructed::
X=IndexedBase('X')
x[3]=sin
Generates an error:
TypeError: 'IndexedBase' object does not support item assignment
