Tobias Pape uploaded a new version of Environments to project Squeak 4.5:
http://source.squeak.org/squeak45/Environments-topa.55.mcz==================== Summary ====================
Name: Environments-topa.55
Author: topa
Time: 21 January 2015, 11:15:37.19 am
UUID: ac4cd9b0-1628-4881-a2c2-f6d1e1a6f089
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.
