EXTRACT()

 FUNCTION: extract(<string>, <first>, <length>[,<idelim>[,<odelim>]])

 Extract returns a string of length words, starting with the first
 word.  Unlike letters, the first word in a string is number 1,
 instead of 0.

 The input delimiter for <string> is <idelim>.  The output list
 delimiter is <odelim>.  <idelim> defaults to a space.

 Examples:
   > say extract(This is a really neat example, 4, 2)
   You say, "really neat"
   > say extract(Another@funky@test@for@extract, 3, 3, @)
   You say, "test@for@extract"
