I just wanted to give a shoutout to AutoLISP and the VisualLISP variant included in AutoCAD. I haven't programmed in AutoLISP for a long time now, but I cut my teeth programming in this built in language. It's kept LISP near and dear to my heart ever since I learned it back in '89. I've often wanted a version of LISP for scripting or utility programming for Windows that was as easy to learn and program with as AutoLISP.
I was excited to modify a script or two in GIMP's scheme and keep a close eye on the LISP community.
