> ... and have been enlightened by SICP and lispey languages,

Fun anecdote: I've got my copy of SICP signed by both authors for Sussman invited me to have tea in his office and when I arrived the next day, by sheer chance, Abelson was there too! They joked that had I been there 30 minutes early Sussman's wife, who proofread the book, would have signed it too! I've got a cool pic taken at that moment: me standing along these two legends and proudly holding the purple book... I'll post that pic and full story the day I have a blog.

Besides that I pretty much live inside Emacs. The occasional elisp (3000 lines of custom elisp hackery over the decades) and lots of Clojure/ClojureScript.
