I was going to post a defence of up-values, but I guess it is too late. Oh,
well.

Out of curiosity, do you plan to do away with upvalues altogether, or offer
both alternatives?

If the former, how is the following handled:

for k, v in tab do
  actors[k] = function(x) act_on(v, x) end
end

I'd be quite content if I can get the existing behaviour by specifying
act_on(%v, x)
