My preferred way is the following:
Add the following method to Object (or somewhere else):
Object>>escaper: aBlock
^ aBlock value: [ ^ nil ]
Then implement your loop like this:
self escaper: [ :break |
1 to: 10 do: [ :x |
x = 3 ifTrue: [ break value ].
... ] ]
Cheers,

Very Smaltalk-ish!
Even works if you want to escape nested loop:
self escaper: [:breakOuter |
1 to: 10 do: [:i |
self escaper: [:breakInner |
1 to: 10 do: [:j |
j = 3 ifTrue: [breakInner value].
(j = 2 and: [i = 7]) ifTrue: [breakOuter value]]]]].
