After playing around with Lisp for a few days I’ve diverted myself back to a small Java project. Almost immediately I’m missing the Lisp environment! To be sure there are some things that I prefer about my Java environment, which is Eclipse, but I just miss having an interactive top-level so much! It’s just amazingly convenient to be able to try sunning a fragment of code, and the ability to tweak it and try again if you hit any problems is such a productvity boost.
