does not work on all platforms

I've investigated exception handling in some depth to implement it in  
GemStone and I don't recall any rules about
returning from a handler. It should just be a block like any other  
Smalltalk block. Good practice, however, is to
explicitly return/resume at the end. I would, therefore, consider the  
following if you wanted to avoid an explicit
method return (^) in the handler:

validate: anObject
	^[ validationBlock value: anObject.
	message contents: nil.
	true ]
		on: self exceptionClass
		do: [ :exception |
			message contents: exception messageText.
			exception return: false  ].
