I have a patch at http://trac.sagemath.org/sage_trac/ticket/14231 . At Nils' suggestion, I actually changed the preparser so that it *always* prints when defining a symbolic function this way. This makes it easier to catch typos like sin(t) = 0 when you want sin(t) == 0. However, this is a nontrivial change in behavior and fixing all the relevant doctests will be a bit of a patchbomb.
