Hi.

Does anybody know why #doesNotUnderstand: is implemented with recursion at the end?

doesNotUnderstand: aMessage��
| exception resumeValue |
(exception := MessageNotUnderstood new)
message: aMessage;
receiver: self.
resumeValue := exception signal.
^exception reachedDefaultHandler
ifTrue: [aMessage sentTo: self]
ifFalse: [resumeValue].

It's so that when a doesNotUnderstand: occurs and one implements the method in the debugger one can proceed.�� The sentTo: at the end will now invoke the newly defined method and one can continue programming.

Best regards,
Denis
