I think you're right that it would have to an option:

   - on the one hand, Option as Meta seems like precisely the right  
choice;
   - on the other hand, Option+letter keys lets you write a lot of greek
     letters and special symbols (including Option-3 for # on UK  
keyboards).

On a related note, am I right in saying that Meta-( ought to insert a  
pair
of parentheses? If so, Cmd-( doesn't do that on my Mac. I can always use
Esc;( but that's more of a pain to key in.
