We need to ensure left-to-right evaluation semantics through and through.
Good. And Walter agrees with you.
Actually he only agrees partially. In the expression:
a[i++] = i++;
Walter argues "evaluate right-hand side first, then left-hand side, then
assign". I argue "evaluate left-to-right regardless". I suspect this
extends to other cases, such as:
functions[i++](i++);
(assuming functions is an array of functions). I argue that LTR is the
one way to go. Not sure he'd agree. Similarly:
objects[i++].method(i++);
(assuming objects is an array of objects). Here again I think LTR is the
simplest and most intuitive rule.
I am not asking for a road map with
dates, but what are the steps and the work to arrive there? What needs
to be done?
I think someone should sit down and define behavior for all such cases,
then proceed and implement it in the front-end. I haven't done
significant front end work so I don't know what that entails.
