To me development with SLIME is much better than with a fast-compiling language.

- Debugger is always ON.

- I can inspect the data I'm working with.

- I can redefine things without starting everything all over, avoid losing current context. Fast restart is not the same.

- I can evaluate pieces of code without the need of a REPL. Point to an s-expression and evaluate that piece of code, inspect the result.

I don't see how Smalltalk is much more interactive. It is more powerful at graphics and tools integration, but SLIME provides an interactive enough experience IMO, and it is significantly better to any fast compiling + restart language.

I prefer Factor for that.
