val backtrackable : 'a t -> Expect.t -> 'a t
val followed_by : 'a t -> Expect.t -> unit t

followed_by p expect

Parses p and backtracks (i.e. all tokens of p will be pushed back to the lookahead). In case p succeeds, the followed_by parser succeeds without consuming tokens. Otherwise it fails without consuming tokens.

val not_followed_by : 'a t -> Expect.t -> unit t

not_followed_by p expect

Parses p and backtracks (i.e. all tokens of p will be pushed back to the lookahead). In case p succeeds, the not_followed_by parser fails without consuming tokens. Otherwise it succeeds without consuming tokens.
