I love thesyntax of Smalltalk and the tools, but I was amazed at how difficult it was to build and deploy a simple GUI application. For example, I just wanted to build a GUI with a text field for entering a name and an OK button. When the button is pressed I wanted to display a dialog box that contains the text "Hello" and the name. The most frustrating parts were the layout of widgets and the packages of the application which involves a large number of steps.+1. It's on my TODO list.
Excellent!
A more recent concern for me is the lack of support for taking advantage of multi-core processors. I know someone is working on improving this.Unfortunately the situation here is rather dire. I blogged about it: http://securesqueak.blogspot.com/2009/03/concurrency.html. It's fully possible to make a Smalltalk VM that does fine-grained concurrency, but nobody concurrently has the time(/money), energy and raw creative intelligence to make one. Until then, Igor's Hydra VM is the best we have. I'd love to make one, but I haven't put it on my TODO list because I don't need a concurrent VM. My single cored 1Ghz Celeron CPU is plenty fast enough. I'm fascinated by concurrent computing, and I've dabbled in it a bit as a hobby, but most of what I do isn't CPU bound. There's a lot of very interesting stuff you can do before you're limited by your CPU speed.
To be honest, it's not so much that I have applications in mind that require use of multiple CPUs as it is fear for the future. While one core may seem fast enough today, what will we think when machines commonly have 16 or more? The thought that I may really be asked to write software that takes advantage of multiple cores has prompted me to start dabbling in functional languages. At the moment my functional language of choice is Clojure. That said, I'd rather work in Smalltalk if it could do that too.
