  I have not seen any papers on it, but those who think about the issue for
  just a few seconds realize that parsing is a stateful process and regular
  expressions are inherently stateless and the amount of state information
  you can thereby employ in the syntax recognition process is very limited.

  Some of the things I want help with when looking at code is to click on a
  symbol name and see its lexical scope and all references highlighted, or
  to show free variable references inside each enclosing scope.  Such things
  are not hard to do if you edit the actual code instead of just characters.
