Towards a different Smalltalk by Boris Shingarov

Alan Kay's vision of Smalltalk was to facilitate the creation of new ideas, as opposed to merely the repeating of more-of-the-same. A given Smalltalk would be one possible Smalltalk, and at the same time it would be a kit enabling the construction of any imaginable Smalltalk. There would be no difference between applications and the system, and the tools would allow you to create a different Smalltalk as easily as a new application. One famous example, is Larry Tesler building the browser in an hour. Opposite to this, almost every Smalltalk today is fundamentally the same Smalltalk-80; almost every browser today is fundamentally Larry's browser.We have grown bored of this. For a few years we have been working on a kit for constructing new Smalltalk systems. In this talk we invite you to join us in building a different Smalltalk which is not a Smalltalk-80. It is a Smalltalk that you can afford to break; instead of enforcing one computational paradigm of unidirectional computation of data "from questions to answers", our Smalltalk reasons about arguments in a bidirectional/equational way; and instead of presupposing the traditional "general-purpose computer" hardware — thus limiting objects to be emulated by sequential processing over "structs" of bytes in memory — our Smalltalk can exploit a multitude of computer structures.
