Will this work for you?
mt = {
 __index = function(tab, k)
 local function f()
 print("You called " .. k .." on "..tostring(tab))
 tab.test = 20 * math.random()
 end
 return f
 end
}
o = setmetatable({ test=1 }, mt)
o2 = setmetatable({ test=1 }, mt)

Thanks to you and David for this suggestion. To answer David's question, yes, it was intentional, however since it doesn't work the way I need it to I suppose I'll just have to change my intention. :-) I'll try this approach. If I can't get it to work I'll come back for more advice. Thanks to you both!
