This means that awkward -- backslashes are not necessary. -- -- You can copy a regular expression in other languages and paste it to -- your Haskell program. -- -- Sample code: -- --
-- { -# LANGUAGE QuasiQuotes, OverloadedStrings #- }
-- -- Due to Haddock limitation, spaces are inserted after and before "}".
-- -- Remove them if you copy this.

-- GHC 6.12.3 or earlier requires the dollar sign before "re".
--
-- GHC 7.0.1 does not allow the dollar sign before "re".

-- GHC 7.0.2 or later allows the dollar sign before "re" as an obsoleted
-- syntax.
--
-- So, use GHC other than 7.0.1 and specify the dollor sign for
-- portability.
