I think the power of a Smalltalk environment is not just the language, and not just the environment. It's the combination of those and the Object Model - the concepts that underlay the syntax. (And a good class library helps a lot.)
I'd like to use a programming environment which has a choice of syntaxes but which uses the same object model. I could enter code in any of the following syntaxes, and see existing code decompiled into any of the following syntaxes:
- JavaScript
- Python
- Smalltalk
- Ruby
- Object Pascal
- RealBasic
- Dylan
- AppleScript
- Eiffel
Interestingly, there is one environment that is approaching the nirvana of multiple-syntaxes with a common object model. Apple's Cocoa, which is implemented in Objective-C, which has an object model inspired by Smalltalk, interoperates with Python, Ruby, AppleScript, and Java. Apple's XCode/ProjectBuilder environment allows writing code in these scripting languages and C/Objective-C/C++/Java/etc.
There are a lot of good Cocoa books out there. My favorite so far is by Aaron Hillegass: Cocoa Programming for Mac OS X It's not a lengthy as the others, and it covers a lot of what makes up a Cocoa application.
