What steps will reproduce the problem?
1. open
<http://code.google.com/p/omega/source/browse/trunk/src/LangEval.hs?spec=svn196&
r=145#213>
2. look at line 213 (marked). It is not highlighted as comment.

What is the expected output?  What do you see instead?
Comment line highlighted as normal code. Should be red.

What version are you using?  On what browser?
Today's running version on google code, Safari 3.1

Looks like
  -- bind x (\ z -> case z of { p -> cont; _ -> fail "matcherr"})
is failing to match the haskell comment pattern.

The comment says 
         // Haskell does not have a regular lexical grammar due to the nested
         // ncomment.
         // comment      ->    dashes [ any<symbol> {any}] newline
         // ncomment     ->    opencom ANYseq {ncomment ANYseq}closecom
         // dashes       ->    '--' {'-'}
         // opencom      ->    '{-'
         // closecom     ->    '-}'

I think I was just confused by the ncomment production when writing the ncomment
production since comment seems to allow '{' and '}' to be contained.

Fixed at revision 73.  Will include this in the next minified version I release 
soonish.
