There is however something lacking for making primitive 103 or cousin work.
A primitive has no idea of how to reach #endOfRun and #crossedX symbols, so
answering hardcoded symbols is of no help, they must be registered
somewhere...

A possibility would be to answer the index. For example, we could encode a:
    stopHelper := (1 to: stopConditions size)
        collect: [:i | (stopConditions at: i) ifNil: [i-1] ifNotNil:
[i\\256]]
        as:ByteArray.

Then test in the inner scan loop:
    (stopHelper at: i + 1) = i ifFalse: [^i + 1]

and in the outer loop:
    [stopIndex := self scanWithHelper: stopHelper.
    self perform: (stopConditions at: stopIndex)] whileFalse.

That would mean restoring some kind of TextStopConditions managing both the
258 stopConditions and the stopHelper... A bit too much to my taste. I
think it's too late for my brain ;)
