So, simply define define a directive which would require a compiler to
either use left-right argument evaluation or refuse compilation (and
define another for right-left), and likewise for evaluation of terms
within an expression.  Any compiler that can honor the requirement could
compile code with that directive.  Those that can't would refuse
compilation.
