As for this, you should be able to take a symbolic expression ex and
do ex._maxima_() to get an equivalent Maxima expression living in the
"calculus copy" of Maxima, which is the one that would be relevant
here since it "knows" some of the other things you've been up to in
calculus in that session. You shouldn't need to make any new custom
code; at worst, the existing expressions conversion code (also in a
few places in sage/symbolic/) might need upgrading. For instance, you
won't be able to do much with anything which needs to evaluate a
derivative at a point - see #385.
