Because RunArray>>scanFrom: basically links all the Text to RunArray
Indeed. Actually, RunArray class>>scanFrom: seems to be used as an utility method. It can perfectly be moved into a different package (as soon as the caller are updated).

I was thinking to simply use a RunArray subclass and specialze its scanFrom: It may also means that RunArray should not be packaged in CollectionArrayed but with Collection-Text.
scanFrom: strm "Read the style section of a fileOut or sources file. nextChunk has already been done. We need to return a RunArray of TextAttributes of various kinds.
