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

Ancestors: Collections-mt.919
Fixes printString representation of Associations and Dictionarys to avoid ambiguous selectors. As a consequence, reevalabuality is not limited any longer.
Examples:
1 -> 2. "--> 1->2"
1 -> -2. "--> 1 -> -2"
Dictionary new at: -1 put: 1; at: 1 put: -1; yourself. "--> a Dictionary(-1->1 1 -> -1)"
