I am a longtime Smalltalk enthusiast, beginning with the BYTE August 1981 Smalltalk issue. My interests in Squeak are varied, but most pertain to moving Squeak up along the blue plane of development. Of particular interest is the generalization of the present simple Booleans to encompass success/failure semantics; defining true macros (in the Scheme/Common Lisp/Dylan sense) for Squeak - moving it more deeply into the realm of programmable programming languages; and creating a general and extensible mechanism for cleanly creating and defining generators within Squeak.

In the meantime, I have developed a fascination with software visualization/animation and have begun developing a debugger for Squeak based on these ideas.

Come visit my website at http://users.ipa.net/~dwighth/ -- I now have the Implementation section (Chapters 26-30) of the Blue Book (Smalltalk-80: The Language and its Implementation; Adele Goldberg, David Robson; Addison Wesley, 1983; ISBN 0-201-11371-6) online, along with Dan Ingalls' Design Principles Behind Smalltalk paper from the August 1981 BYTE, and more goodies.

A few of my thoughts on Squeak can be read in part of Place in the Universe.

I welcome any questions, thoughts, or just general discussion concerning how to move Squeak toward the blue plane.
