    happy/alex/examples  haskell.x 
  Log:
  A basic Haskell 98 lexer using the new Alex.  This one includes a
  wrapper which just counts tokens, so I can keep an eye on performance.
  
  The lexical syntax is correct w.r.t. Haskell 98, except that it
  doesn't handle Unicode (yet), and there's no layout processing, and I
  haven't tested it with a real parser so there may be bugs.  I have
  shoved a lot of Haskell code through it, though.
