Axel, thanks. This is the critical point, so no apologies needed for
belaboring.
Allen, what I mean is exactly what Axel says here.
Look at it another way. Right now we have two normative modes: ES5 strict
and ES5 non-strict. State machine aside, ES6 introduces a new single mode
normative spec. If the state machine may delegate to any of these three
normative specs we have three modes. If the state machine may only delegate
to ES5-non-strict or ES6, i.e., if the ES5-strict spec becomes dead code as
of conformance with state machine + ES6 spec, then we have two modes.
To get this effect, we need only classify ES5's "use strict"; directive as
ES6-only. If any objection to doing so has been stated, I missed it. Is
there a reason not to do so? It's a one line change that leaves the rest of
your proposal unperturbed and solves this problem.
