Helper functions for defining certain instances of RegexContext. These help when defining instances of RegexContext with repeated types:

instance (RegexLike regex source) => RegexContext regex source source where

runs into overlapping restrictions. To avoid this I have each backend define, for its own Regex type:

instance RegexContext Regex String String where
  match = polymatch
  matchM = polymatchM
instance RegexContext Regex ByteString ByteString where
  match = polymatch
  matchM = polymatchM


polymatch :: RegexLike a b => a -> b -> b Source #

polymatchM :: (RegexLike a b, Monad m) => a -> b -> m b Source #
