Hi Guys,

I believe the Ring metamodel has been proposed 4 or 5 years earlier.
Is it acctually in use in the current pharo tools? which ones?

I have been told that Martin has develloped a different model : Ficus
What are the limitations that Martin tried to fixed?
What can be further unhanced?

Thanks.

Abdou.
