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

Name: Environments-topa.55
Author: topa

Ancestors: Environments-topa.54

3rd attempt at class-rename fixes.

This version
 a) avoids #becomeForward:
 b) fixes method homes after rename
 c) moves the obsolete binding to undeclared but keeps it working.

Effectively, this is the outcome:
| p |
p := Object subclass: #A instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'Unknown'.
p compile: 'foo ^ A new'.
" literals of #foo {#A=>A . #foo . #A=>A}"
p rename: #B.
" literals of #foo {#A=>B . #foo . #B=>B}"
p new foo class == p.
