Changeset: r84:235293a3b353
Date: 2013-02-21 15:44 +0100
http://bitbucket.org/pypy/lang-smalltalk/changeset/235293a3b353/
Log: (cfbolz, lwassermann around): stop using unwrapped strings as values
and just compare them by identity, which Squeak guarantees to be
unique.
this actually makes the behaviour more correct, because now doing
nasty stuff like manually changing the symbol won't break method
dicts.
