The way I use it, this implies a strong limitation of squeak; each
algorithm with intensive mathematical computation will need a
dedicated primitive...

So, I understand that I need:
- intermediate classes, for storing 'true' arrays,
- translators for converting to/from standard squeak classes from/to
these intermediate classes,
- primitives for array computation on these classes
or something like that.

A lot of work...
Are there people, which have already done a part of the job? Or are
interested by such classes and primitives?
