Consider proxy tables. You never actually add anything to the proxy

t = {}
proxy = {}
setmetatable(proxy, {__index = t, __newindex = function(_,k,v) t[k] = v end})
[I think you can actually just set __newindex to t, but this should
work regardless.]

In that case, your example still works: not returning anything results
in returning a nil; this will then set a nil in a table: which does
nothing
ALso, you can't set __newindex to a table: that only works with
__index (Though it would be a nice improvemet if there is no
performance loss)
