Description
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
instance RegexContext Regex Text Text where match = polymatch matchM = polymatchM
