Martin Fowler has some interesting things to say about static and dynamic typing. It's not arant, and it's not an evangelical piece, either. Here's an interesting segment, but I'd suggest that you read all of it:
Another area where static typing is useful is that it allows programming environments to be much more helpful. The revelation here (as in so many things) was IntelliJ. With an IDE like this I really felt the type system was helping me. Even simple things like auto-completion are greatly helped by static types, and leading IDEs can do much more than that.
Despite this, there's still something particularly satisfying about programming in languages like Smalltalk and Ruby - and I think it has a great deal to do with the dynamic typing. Chatting at Camp 4 Coffee with Bruce Eckel we both agreed that one of the most frustrating things about the static/dynamic typing debate is that it's very hard to put into words the advantages of working in a dynamically typed language. Somehow things just seem to flow better when you're programming in that environment, even when I'm doing my Ruby in emacs instead of IntelliJ. (Smalltalk, of course, has both the language and a lovely programming environment.)
Mind you, there are loadable components for VisualWorks that give you auto-completion.
