- There are several departures from Smalltalk’s syntax and semantics. The most notable of these are: no explicit returns, 0-based indexing, no metaclass hierarchy, special syntax for instance variables.
- Cæsar is a system browser built on all of the above. Like Clamato, it departs in a few notable ways from traditional Smalltalk browsers, but retains their spirit.
