Following up:
Behavior new compile: 't ^ true’
fails since #compile: is defined in TBehavior and depends on
#basicLocalSelectors which is defined only in Class, MetaClass and
TraitBehavior.
It seems like #basicLocalSelectors should be abstract in TBehavior.
Alternatively the implementation should be moved to TBehavior and the field
localSelectors should be pushed up to Behavior. Am I missing something?
