Detailed Description

Marks locations of code or data area of the program.

Labels are owned by scopes. Scopes do not provide methods to add new labels, because the labels are automatically registered to a scope by their constructor: a label cannot exist without its scope.

A label must have a unique name within the owning scope. It does not matter if there are other labels with the same name in outer scopes, because the inner scope has precedence. As a result, all labels in global scope must have a unique name.
