{-# LANGUAGE TemplateHaskellQuotes #-}

-- | QuasiQuoter for non-interpolated strings, texts and bytestrings.
--
-- Originally by Audrey Tang <audreyt@audreyt.org>
--
-- The "s" quoter contains a multi-line string with no interpolation at all:
--
-- @
-- {-\# LANGUAGE QuasiQuotes #-}
-- import Data.Text (Text)
-- import Data.String.Quote
-- foo :: Text -- "String", "ByteString" etc also works
-- foo = [s|
--
-- Well here is a
--     multi-line string!
--
-- |]
-- @
--
-- Any instance of the IsString type is permitted.
