Yeah, except without all the bad parts like images that can get corrupted
Sorry, I've been a professional in Smalltalk since 1998, and I've never encountered a corrupted image. The closest thing I've seen to that is de-sync with source code. (Which you don't care much about if you're using SCM, for the same reasons everyone else uses SCM.)
stateful (wtf were they thinking?) web-apps.
Same things others were thinking at the time -- you're just seeing a slice of history. People still rave over the debugging in Seaside like it's magic, though.
All the benefits of a Lisp REPL and a Smalltalk debugging environment in a language people actually use. Tab-completion, dumps, breakpoints, testing assumptions/data, running arbitrary code inside a specific environ...the works.
I can use it in my virtualenvs without having to explain to an IDE what a virtualenv, a running test in Nose, a normal script, or a running web server. It's normal code so I can wrap the trace in a condition or whatever else I want.
No, I'm wondering if the promulgators of Smalltalk as a superior debugging environment actually have anything superior to what I just described so that I can steal it for Python.
Sometimes I toss stuff out there in the hopes of being shown something better. It's teaches me new things.
Lets take a moment to think on our poor brethren still tossing print statements all over the place though.
(I've often said around here that things would've worked out better if there wasn't such a barrier between stuff happening in Smalltalk and outside in the OS -- community wise. But if you're willing to play just in the Smalltalk sandbox, it's a pretty awesome experience.)
I've only used Smalltalk/V during university, back in 1995, if memory serves me right.
I've seen integration problems migrating code between implementations, lack of proper support for source control specially in distributed teams, lack of integration with the operating system for desktop applications.
I know that many of these problems have been solved in newer implementations, but maybe now it is too late.
