For simple static highlighting, a lexical analysis is more than
adequate. (You've seen http://www.cs.york.ac.uk/fp/darcs/hscolour,
right?) You only need a full parser if you want to do (e.g.) hyperlinks
from a variable usage to its definition site. (You seen Programatica as
well, http://www.cse.ogi.edu/~hallgren/h2h.html right?)
