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

Name: Kernel-eem.1139
Author: eem
Time: 10 January 2018, 5:37:26.591853 pm
UUID: 54bd97b7-0152-4647-b109-78c294afc74e
Ancestors: Kernel-eem.1138

Add CompiledBlock>>pragmaAt:.  Make the accessors that defer to the home mehtod use homeMehtod instaed of chaining through outerCode.  The stack depth is one less as a result.
