[Cuis] Wrapper for file access in different Smalltalk dialects

Hi Masashi,
Recently we found that in FileMan, if we do
'inexistentFile' asFileEntry readStream
we get an empty readStream.
I think it is better to throw the #fileDoesNotExistException , as
FileDirectory did, and let the user handle the exception appropriately.
But I would not want to break compatibility with FileMan, as the main
purpose of FileMan is to give compatibility amongst dialects.
Are there good reasons to avoid the exception? Should we add another
method, besides #readStream when we want a readStream strictly on
existing file contents?
Thanks,
Juan Vuletich
