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.
