Hi,

I guess you can claim this is a proposal but I also want feedback on it...

The idea is new semantics for __newindex so you can use it without rawset():

function __newindex(t,k,v)
  if condition then
    return k,nv
  elseif othercondition then
    return nk,v
  elseif anothercondition then
    return nk,nv
  else
    return k,v
  end
end

Unless your __newindex returns junk, this shouldn't break anything.

Thanks.


I think the biggest argument against this is that it only applies to tables. What about userdata? Having the added complexity of tables be a special cases doesn’t seem to be warranted by the minor convenience.

For userdata it would end up in an attempt to rawset(ud,k,v) :P
