In any programming language, is the type of referencing environment dependent on the scoping? i.e. a static scoped language would necessarily have static referencing environment?
回答1:
Yes. The referencing environment is the collection of variables which can be used. In a static scoped language, you can only reference the variables in the static reference environment.
A function in a static scoped language does have dynamic ancestors (i.e. its callers), but it can not reference any variables declared in that ancestor.
