An interesting post appeared on the VSE (Visual Smalltalk Enterprise) mailing list recently; here's the description:
The original Visual Smalltalk dialect by Digitalk has survived ten years of proclaimed discontinuity. Paradoxically, the languishing commercial interest in this legitimate successor of the Smalltalk lore had a positive consequence: it protected the product from sophistication. After stripping out the over dimensioned Envy-like Enterprise development environment, and forgetting the PARTS that nobody seemed to use in real projects, we are left with a simple, powerful, compact and fast Smalltalk implementation. Even though Visual Smalltalk does certainly have a prominent history, it is neither perfect nor finished. As it is usually the case with every corpus of fruitful intellectual work, there are still many interesting details waiting to be completed. To begin with, there is one crucial problem in Visual Smalltalk: it has a bunch of hidden classes and methods that nobody has disclosed so far. This document is an attempt to repair that historical mistake. It explains how to recuperate all hidden classes and how to retrieve all missing Smalltalk source code.
The mail came from Leandro Caniglia; here's a link to the document he posted. It's a Word document, about 86k.
