Self 4.3

There is a new release of Self out. It is not that new, but I have just heard of it. Self is one of the original prototype-based languages. It features a runtime optimizing compiler which profiles your code and inlines the methods called most; also its Morphic UI heavily inspired Squeak's Morphic UI. Self comes from Sun labs. While Java's HotSpot compiler is heavily influenced by Self, the UI and interactive development environment never made it into any of the mainstream languages.
