I have met at least one ES6 enthusiast who found AssignmentExpression difficult to understand while trying to learn more about arrow functions. Can we replace all uses of AssignmentExpression except one or two to say, Expression[nocomma]?
Even better, if spec-wise backwards compatibility is not a problem, could we just replace AssignmentExpression by Expression and the current Expression by Expression[comma]. I think it better matches the mental model of a normal programmer like me. Also, Java doesn't seem to allow top level comma in Expression at all[1]. Speaking of which, shouldn't we use AssignmentExpression for TemplateLiteral instead of Expression? It's not like we must parse a full Expression within a balancing pair (we only allow AssignmentExpression between '?' ':', unlike C[2] and C++[3]). Leaving an extention point there for the future seems better. What do you think?
