& escape()
 
  Syntax: escape(<string>)
 
  Returns <string> after adding an escape character (\) at the start 
  of the string and also before each of the characters %;[]{}\ that 
  appear in the string. This prevents strings entered by players from 
  causing undesired side effects when used, such as making your 
  object perform unintended commands or give out information to which 
  you have access. 
 
  Note that this function is only needed when the resulting string is 
  to be passed through the @force command or be used as an attribute 
  for an object (like the success message for a mail message object). 
  This function has the advantage over the secure() function in that 
  the string the user sees after evaluating it is the same as the 
  original string.
 
  Example:
 
  You say "\Sneak a peek at Wiz's desc... \[get(#1/desc)\]"
 
  Note: 'say escape(Sneak a peek at Wiz's desc... [get(#1/desc)])' 
  does not produce the expected result because the argument is 
  evaluated BEFORE being processed by escape(), therefore the get() 
  call has already been performed.
