# This module keeps track of arbitrary "states" at any point of the code.
# A state is considered known if every path to the given point agrees on
# its state, otherwise it is None (i.e. unknown).
# It might be useful to be able to "freeze" the set of states by pushing
# all state changes to the tips of the trees for fast reading. Perhaps this
# could be done on get_state, clearing the cache on set_state (assuming
# incoming is immutable).
# This module still needs a lot of work, and probably should totally be
# redesigned. It doesn't take return, raise, continue, or break into
# account.
