Nah, the result has nothing to do with #on:do: resuming with 1, you better
[('abc' + 1) + 1]
do: [:e | e resume: -1]
which still says 2. This because someone, behind you back, put #asNumber
arithmethic into ByteString ... now this attempts (Number readFrom: 'abc')
which gives 0 for your +1 +1 and so 2.
You may want to start DNU testing with ('abc' break; + 1) and then see
where it goes.
