By this, you mean move the "base" vector/matrix objects from there into
Pharo?  This makes a lot of sense.  These are applicable to a lot of
applications, and having them in-Image obviously helps focus efforts and
reuse.  These could just have the minimal methods required by Bloc, with
PolyMaths/SciSmalltalk extending them with more exotic operations.

Good initiative, and already getting to useful collaboration.

btw, I know sharing opens up to nit picking that can be discouraging, as
we've seen other tools you've introduced in the past get a bit of a beating
at the transition stage - but your vision and good work has borne through
and now these are tools we now can't live without!   So keep up the good
work.
