I have 'bisected' and the #workingCopy
was introduced in 2011:

Name: Monticello-cmm.436
Time: 10 March 2011, 1:46:11.144 pm

- Added several methods for tracing MethodReferences and Classes back to their MC counterparts; their #workingCopy, and #repositoryGroup.
- Ability to convert MethodReferences to equivalent MCMethodDefinitions, and classes to MCClassDefinitions.
- Added MCRepository>>allVersionsDo:.


Chris, what PackageInfo do you have that injects #packageInfo into Class and MethodReference?
I've looked in several images and repositories and cannot find a PackageInfo that
provides those :/
