I believe the simplest way to do it would be to have an extra preprocessing
pass... it will slow down compilation a little, it's true, but maybe not that
much as to matter (compilation is anyway so much faster than the downloading

then you can have two different, and simpler, lexers to do the job...
i suppose this won't get very high priority on your list, Dave, so I will try
to do it myself and wil let you know how it goes.
