Examples of StaticScope

org.jruby.parser.StaticScope
StaticScope represents lexical scoping of variables and module/class constants. At a very high level every scopes enclosing scope contains variables in the next outer lexical layer. The enclosing scopes variables may or may not be reachable depending on the scoping rules for variables (governed by BlockStaticScope and LocalStaticScope). StaticScope also keeps track of current module/class that is in scope. previousCRefScope will point to the previous scope of the enclosing module/class (cref).
