úÎäNoneIA quasiquoter for raw string literals - that is, string literals that don't 1recognise the standard escape sequences (such as '\n'). Basically, they Nmake your code more readable by freeing you from the responsibility to escape Gbackslashes. They are useful when working with regular expressions, DOS/Windows *paths and markup languages (such as XML). Don' t forget the LANGUAGE QuasiQuotes pragma if you're using this module in your code. Usage:    ghci> :set -XQuasiQuotes # ghci> import Text.RawString.QQ  ghci> let s = [r|\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,3}|]  ghci> s  "\\w+@[a-zA-Z_]+?\\.[a-zA-Z]{2,3}"  ghci> [r|C:\Windows\SYSTEM|] ++ [r|\ user32.dll|]  "C:\\Windows\\SYSTEM\\ user32.dll" 2Multiline raw string literals are also supported:    multiline :: String  multiline = [r|<HTML>  <HEAD>  <TITLE>#Auto-generated html formated source</TITLE>  <META HTTP-EQUIV=" Content-Type" CONTENT="text/html; charset=windows-1252">  </HEAD>  < BODY LINK="0000ff\" VLINK=\"800080" BGCOLOR="#ffffff">  <P> </P>  <PRE>|] Caveat: since the "|]"- character sequence is used to terminate the quasiquotation, you can',t use it inside the raw string literal. Use  if you =want to embed that character sequence inside the raw string.
