It may not be viable for "real" programming, but what I like these days is to just write some code without even trying to think too clearly about what I am doing or the details, and sprinkle asserts that encode how things should be if I was following what I am doing.

Then I run it interactively with source debugging and when anything goes wrong, I do some editing and more than half the time I don't even have to restart the program from the beginning.

And the more subtle the things I "assert" the more direction I get when they are violated. It eliminates a lot of effort in sorting out incorrect ideas when I can just encode my incorrect ideas and let the computer find the problem.

I've always shied away from Lisp and similar, but I'm definitely reminded of how advocates describe the benefits of developing in an interpreted environment. When I was a kid, I always had the sense that only compiled languages were prestigious, industrial strength, professional, whatever.
