If you carefully consider the scope in either case you will notice that
there is no other than the "this" or "self" (or whatever you call it) scope,
so no need for it as keyword to specify the only available scope.  In
particular because every attribute of the object would be a reserved name
anyway, so no need to disambiguate between local and global variables
either.  Essentially what I am pointing out is that the concept of "this" or
"self" simply does not apply to POV-Ray SDL.

As we are talking about the future so am I.  Just imagine every expression
being a function rather than a macro.  Then you would apply the changes to
the object after everything is well-defined and order problems would not
exist.
