That's really hard in practise you have to make any symbol that selects
something depend on the dependencies of the selected symbol.  You can't
do this without involving a SAT solver.  A guy promised to do this a
couple of years ago, but the patches never materialised.  However, they
may exist somewhere if someone wants to take a look at completing it.
