Comment #9 on issue 3545 by [email protected]: FEATURE: Multiple Worlds http://code.google.com/p/pharo/issues/detail?id=3545
Multiple worlds is a piece of functionality that I missed from Squeak, and pushed to get back. It doesn't do any of the other things that projects do. Although, Pharo seems to be open to any code that is clean, especially if well-documented and tested, so if you miss some other feature, code up a prototype and get people excited about it :)
