yeah, i actually like to break them out like

	%r|
            GET
            \d\d\d\d  # year
            \d\d      # month
           |

but i didn't want to go overboard!

named captures are a real want in ruby right now if you ask me.  i've  
been using the idiom

   match, yyyy, mm, dd, *ignored = pattern.match(string).to_a

   if match
     ...
   end

as a workaround

(for those that don't know the captures in patterns can be got that way)

cheers.
