Self is an object-oriented programming language based on the concept of prototypes. Essentially an extreme dialect of Smalltalk, it was used mainly as an experimental test system for language design in the 1980s and 1990s. In 2006, Self was still being developed as part of the Klein project, which was a Self virtual machine written fully in Self. The latest version is 4.4, released in July 2010.
Several just-in-time compilation techniques were pioneered and improved in Self research as they were required to allow a very high level object oriented language to perform at up to half the speed of optimized C. Much of the development of Self took place at Sun Microsystems, and the techniques they developed were later deployed for Java's HotSpot virtual machine.
At one point a version of Smalltalk was implemented in Self. Because it was able to use the JIT this also gave extremely good performance.
Self was designed mostly by David Ungar and Randall Smith in 1986 while working at Xerox PARC...
