They are different according to the ANSI standard. When an exception is
resumed from an outer, the resumption occurs at the #outer message send, not
the original #signal. For example, consider

outer : 
	[Notification signal. 4] 
		on: Notification 
		do: [:ex | ex outer. ex return: 5]

pass :
	[Notification signal. 4] 
		on: Notification 
		do: [:ex | ex pass. ex return: 5]

In the first example, the resume occurs for the "ex outer" statement so the
"ex return: 5" is executed and the overall expression returns 5 (according
to ANSI). However, in the second, the resume occurs for the "Notification
signal" and "4" is returned. If the exception isn't resumable, then they
should behave the same.
