We should have the super-useful `manyTill_` combinator. [`Combinators.manyTill_`](https://hackage.haskell.org/package/parser-combinators-1.2.1/docs/Control-Monad-Combinators.html#v:manyTill_) ```purescript manyTill_ :: forall e m a s. Monad m => ParserT s m a -> ParserT s m e -> ParserT s m (Tuple (List a) e) ``` Also ```purescript someTill_ :: forall e m a s. Monad m => ParserT s m a -> ParserT s m e -> ParserT s m (Tuple (List a) e) ```
