Overview

ObjectInspector::Scope defines a predicate method that matches #name and responds with ‘true`. This is a prettier way to test for a given type of “scope” within objects.

It is possible to pass in multiple scope names to match on. ‘:all` is a “wild card” scope name, and will match on all scope names. Passing a block to a scope predicate falls back to the out-of-scope placeholder (`*` by default) if the scope does not match.
