With this, we can just highlight the bindingElement when the temp variable
for it is assigned.
Note there are few scenarios like below which would still highlight let part
but thats because of how default value source mapping is currently which is next
in pipeline to support binding element with default values
for (let {name: nameA, skill: skillA } of robots) {
console.log(nameA);
}
or
for (let [numberA2, nameA2, skillA2] of robots) {
console.log(nameA2);
}
