Frank Shearar uploaded a new version of Kernel to project The Trunk:
http://source.squeak.org/trunk/Kernel-fbs.697.mcz

==================== Summary ====================

Name: Kernel-fbs.697
Author: fbs
Time: 8 June 2012, 2:58:00.068 pm
UUID: bcec51c0-7e42-4f78-897b-73b99f088354
Ancestors: Kernel-nice.693

* The resolver instvar is initialised to an Array so #ifNotNil: is a no-op.
* #evaluateResolver: reimplemented #cull:; rather use BlockClosure's version - less duplication.
