*@Rob:* Thanks for pointing out "proposal-bind-operator". I examined the proposal and as far as I understand, it is just another way to create a bound enclosing function. What I am proposing is just the opposite, no binding should take place in the enclosing function. A method call or usage of a property should already have its lexical scope pointing to the class instance and should not need any binding of its enclosing environment to function correctly.
