Now I'm getting into Smalltalk 'for real' and finding that the OO-ness of it is not even the main thing I find compelling: it's the live-ness of it. It's just easier to think about the abstractions 'in the present' as it were.
I think Smalltalk takes the idea of live objects to such a level of sophistication that most people can't quite grok the Platonic Forms of domain modelling that swirl around the mind of an accomplished Smalltalk developer.and also
But folks who have come to think OO is more buzzword than reality could not possibly have tried Smalltalk, not 'for real,' let alone tried to get good at it. It's not just a language or even a platform but a way of thinking about reduction of a problem to its essence, as this article makes clear.I did leave out the bit in the middle where he has some thoughts for improvements like pattern matching, but they're at the bottom of the article. For myself I've never quite seen pattern matching as an especially valuable feature. To my mind the biggest gain is that it's a terse way of extracting out elements of a list -either a variable size list of arguments, or if you're in a language where linked lists are the primary data structure, being passed a list and automatically having it expressed as two variables represent first and rest. Other than that it just seems like syntactic sugar for a case statement. But maybe I'm missing something.
