|Summary||0007250: Object>>#doesNotUnderstand: incorrectly handles a resumed MessageNotUnderstood|
The implementation of #doesNotUnderstand: in Object does not check whether the signalled MessageNotUnderstood has been resumed and return the resumed value. Instead it simply resends the message. As a result, this will loop forever:
" should evaulate to 'abc' " [Object new foo] on: MessageNotUnderstood do: [:e | e resume: 'abc']
This may be an issue in versions earlier than 3.10.

It is not identical to the VW code, but it is essentially the same solution. The solution is pretty obvious, so I don't think there will be any issues.
