Thanks Dale. But that only works for Integers. I am looking for a
polimorphic way for all type of byte-objects that are not
SequenceableCollection subclasses. Float, Character, LargeInteger, Integer
etc. OK, I do have the polimorphic way to get all bytes and write it to the
binary stream using  #_basicSize and #basicAt: . But then I am missing the
materialization part. Actually, I miss the instance creation method to
create an instance with a concrete size, so that I can then do the
#_basicAt:put:

Thanks,
