Since a table is a single-dimension thing, as I see it, the third line should also call __index (even if there is already something at eg t[1*rowsize+2]). I mean the multiple-index semantics are app-specific, implemented in __index; & Lua is not supposed to interpret it, thus for the language t[i,j,...] always fails and __index gets called. But maybe I don't properly get the intent of the proposal.
