In the case of the original post, however, you *need* to use this.value, 
as the parameter masks the member of the same name. Using 'this' removes 
ambiguity.

This is a typical pattern seen in many languages. Often the intuitive 
name of a member is the same name as you want for the parameter of the 
constructor.
