addCaptureNamesToMatches :: CaptureNames -> Matches a -> Matches a

a convenience function used by the API modules to insert capture names extracted from the parsed RE into the (*=~) result

addCaptureNamesToMatch :: CaptureNames -> Match a -> Match a

a convenience function used by the API modules to insert capture names extracted from the parsed RE into the (?=~) result

addCaptureNames :: Typeable a => CaptureNames -> a -> a

a hairy dynamically-typed function used with the legacy (=~) and (=~~) to see if it can/should add the capture names extracted from the RE into the polymorphic result of the operator (it does for any Match or Matches type, provided it is parameterised over a recognised type). The test suite is all over this one, testing all of these cases.
