Is there any interest or plan in porting Artefact to other Smalltalk dialects? 

We would prefer to improve it :)
and build on top.

I image there would be few dependencies to deal with, like UnitValue.

I've worked with PDF4Smalltalk on VW, but porting it proved be a challenge because of namespace collisions (it has classes Boolean, Integer, Date, etc).  

why we ported Moose to Pharo and we handled the namespace.


Thanks,
