Does anyone have suggestions for interesting programming languages to try?
I set a goal to write code in 100 different programming languages (solving Project Euler problems). Right now, I'm up to 35 (mostly old/obscure).
Favorites so far: SectorLISP, Piet, BBC BASIC, Unison, PostScript, Factor, Rebol, Turbo Pascal, and... SIC-1 Assembly Language, of course!
