The simplest way is to factor your code such that when you are done processing in your loop, you answer from the method when you've reached that.
contains: anItem
self do: [:each| "some stuff here if you want" anItem = each ifTrue: [^true]. "breaks the loop, returns true to caller" "some more stuff here if you want" ]. ^false "default answer if not found"
I'd suggest trying to get your code shaped like that. It'll be the most familar.
There are more complicated ways to do it with exceptions if you need to stay within the same method. Don't do that. :)
