#2When clojure meets smalltalk

#3I really, really like Clojure. I just wish I had something to use it for. I've done lots of Common Lisp development previously and REPL-based programming is just great. I can't really do it in Python and it makes me sad.

That really bugs me with a great many popular languages. There's a REPL, but the libraries and tooling don't really embrace it.

Yeah, PHP supports a REPL too! I sometimes found it useful when working on mediawiki to debug issues when a full blown debugger wasn't necessary. And if you were familiar with the various internal API's it was pretty easy to do simple maintenance tasks through the REPL without needing to write a script.

The only tools I've found with decent support for Python and other languages are all emacs based. Same goes for the Clojure and CL ones, actually. It's no surprise, I suppose, because this style of programming is so natural to an emacs user.
But it's difficult with Python as soon as you try to do anything beyond a single module. CL and Clojure have proper packages and namespaces so it works fine. But in Python you're limited to working on the context of a single module. If you modify a module that was imported then you have to restart the REPL because you can't reload modules. It just doesn't work.
In CL I would just load the entire system then eval whatever part I want to. From that point I would never not have the current version of the system completely loaded into the running image. Much the same with emacs itself. It is a running image of your emacs lisp system and you can just modify it and eval as-you-go. Does any other language even come close to this?

Interesting. But one of the points of Clojure is to get away from the object-oriented way so I'm not sure that I'd like Smalltalk.

Re: Clojure REBL [video]
#10Wish he had released the tooling. The REBL system looks a bit like the smalltalk virtual machine mixed with elements of Elm's time-traveling debugger. There has been a real need for serious error handling in clojure for a long time (since the stack traces and exceptions are borderline unintelligible). This thing makes it look much more user friendly.
They tried to fix the errors with Spec but honestly I don't think that solution worked that well. Spec is great for generative testing and other solutions but no one wants to write specs for every single small little potential error that could happen.
