but.. if the code says "for i,v in pairs(t) do" then the overloading would work already now?

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

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.
