It is already half-way towards a 'using' statement, i.e. something
that could guarantee finalization of the given object.

True, but static analysis is already hit-and-miss in Lua.

The trouble (as with Pascal with) happens when such such constructs
are nested.  Would this statement nest as expected, i.e.

   in e1 do in e2 do
     -- will fallback to lookup in e2, then e1
   end end
