    val maybe_shift_t : state ->
           terminal ->
           state option

`maybe_shift_t s t` determines whether there exists a transition out of the state `s`, labeled with the terminal symbol `t`, to some state `s'`. If so, it returns `Some s'`. Otherwise, it returns `None`.

    val may_reduce_prod : state ->
           terminal ->
           production -> bool

`may_reduce_prod s t prod` determines whether in the state `s`, with lookahead symbol `t`, the automaton reduces production `prod`. This test accounts for the possible existence of a default reduction.

           nonterminal ->
