I'd like to get confirmation from someone with an older version of Opera 
about what works and what doesn't.  My recollection is that the patch 
made Opera 9.27 happy - even though it didn't remove all literal regular 
expressions.  You'll note that we had literal regexes in literal objects 
in 2.7 as well.  Hence my request for someone to check 2.7 in the same 
version of Opera.

If nobody has Opera 9.27, I'll look at reverting mine.  Though this does 
add weight to the opinion that the effort is a bit quixotic.
