Nicolas Cellier uploaded a new version of Traits to project The Trunk:
http://source.squeak.org/trunk/Traits-nice.285.mcz

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

Name: Traits-nice.285
Author: nice
Time: 22 March 2010, 10:49:41.743 pm
UUID: 1bedcfe1-f6f6-9a4a-93ed-dcf553a62596
Ancestors: Traits-nice.284

Use literalEqual: rather than = to test for compiled code equality.
We don't want 256000.0s1 = 256000.0e0 nor = 256000
