"doesn't it make very hard to wrap your head around complex code bases after they grow beyond what you can keep in your head at the same time (as any other dynamically typed language)?" - I'd say Smalltalk's really nice simple development environment, with the debugger being super easy to use, saves your bacon here. I always found it very easy indeed to inspect code, find out what it's doing. And there was less code in the first place. I think you raise a valid concern, but other strengths of the language and its development environment make this less of an issue than it might be. Somewhat hard to explain - best to download Pharo, read Pharo By Example, and have a play :)
