Not ony dangerous, it will not work in all cases - i.e.:

Your index method should return a function that when called
will call all the functions in the mdp.  Something like:

function mdp_index(mdp, name)
    local f = function(...)
        for i=1,getn(%mdp) do
          call(%mdp[i][%name], arg)
    mdp[name] = f  -- cache result
    return f
