In a lot of cases... probably not in my experience. I think it can make a big difference in some cases though. What REPL were you using though? Something to think about is that the Lisp and Smalltalk REPLs are a lot more powerful than Python in that I think when an expression fails, the program itself can be edited and it will start where it left off. You can't do that with Python. Edit: the article does a good job of explaining this as "It's like if you could run your code in a debugger with a breakpoint at every single line that only activates if something goes wrong!"
