Why so complicated?
   pairs = function( t )
        local mt = getmetatable( t )
        return ( ( mt and mt.__pairs ) or raw_pairs )( t )
    end


It would be very cool if 'for i,v in t do...'
would use the global pairs() function;  that would
(a) make quite explicit what the for-loop means
if t isn't an iterator function and (b) make interesting
overloading possible, such as above.
Well, it uses the global next() function, isn't that kind of good enough? Try [[next = nil for i,v in t do ... ]]. It's also deprecated.
I asked for these two facts to be documented ages ago (close to when 5.0 came out?).
