What about the following:
Functions with return AssignmentExpression that include "=" and without--are
the ones without also confusing without the "necessary" visual cue?
function a() {
var F;
return F = function() {};
}
function b() {
var C;
return C = class {};
}
vs.
function c() {
return function F() {};
}
function d() {
return class C {};
}
Or yield in generators?
function * a() {
var F;
yield F = function F() {};
}
function * b() {
var C;
yield C = class C {};
}
vs.
function * c() {
yield function F() {};
}
function * d() {
yield class C {};
}

Isn't that exactly what I said? You asked "So why are we?", I answered "To
make a single form that works across platforms" and added that amd and cjs
don't "just work" together. Then I concluded by with a specific example,
but surely that wasn't too misleading?
