Text.Regex.Do.Pcre.Ascii.MatchHint

Description

this module uses TypeFamilies

this module is similar to Text.Regex.Do.Pcre.Ascii.Match. The differences are:

Text.Regex.Do.Pcre.Ascii.Match is more flexible:
accepts Pattern Regex,
accepts Pattern and Body of different types
Text.Regex.Do.Pcre.Ascii.Match needs to infer result type

this module:

Pattern and Body are of the same type
Hint and inferrable Pattern or Body type determine the instance
the result type is determined by the hint
handy when working with OverloadedStrings, in other cases when compiler needs a hint
