The Inbox: Kernel-hmm.441.mcz

A new version of Kernel was added to project The Inbox:
http://source.squeak.org/inbox/Kernel-hmm.441.mcz

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

Name: Kernel-hmm.441
Author: hmm
Time: 16 April 2010, 10:19:20.499 pm
UUID: a3347ac6-2e2b-4deb-a8db-dd9c24d3e0f2
Ancestors: Kernel-cmm.440

Proposal: wrap the parsing action in CompiledMethod>>methodNode in a SyntaxErrorNotification error handling block to decompile methods which can't be parsed correctly.
OMeta2 and probably other domain specific languages benefit from this.
