  This tests ODR for how we wrap our Python.
  This is tested explicitly with symbolic::Variable, given that it has global
  state, and ensures that we have unique symbols generated from two different
  modules in sequence. If we fail this, then that means we have multiple
  definitions of `drake::symbolic::Variable::get_next_id()`.
