Description

For example

public class Outer {
public class Inner {
public String debug()

{ return "inner debug"; }

}
}

The following won't compile:
def outerinner = ['debug':

{return "overridden debug"}] as Outer.Inner
println outerinner .debug()

Caught: org.codehaus.groovy.runtime.typehandling.GroovyCastException: Error casting map to TestInner$Inner, Reason: Error creating proxy: startup failed, Script1.groovy: 1: unexpected token: $ @ line 1, column 12.

Tried to use:
import Outer.Inner as MyInner;
def outerinner = ['debug':{return "overridden debug"}

] as MyInner

import Outer.Inner;
def outerinner = ['debug':

{return "overridden debug"}

] as Inner

both do not work.
