Anyway, I started looking through it for interesting articles, and found that I tend to gravitate towards functional ones. I'll put some links here, but maybe if folks wanted to they could look for interesting papers and share something about them at the meeting? Here are some I found interesting:
(Incidentally, Dijkstra had called it "A Case Against the Goto Statement", but Niklaus Wirth, the editor of the ACM at the time, gave it the meme-forming title we know it by)
P. J. Landin's "The Next 700 Programming Languages" from 1966, presenting a theoretical language called ISWIM that was more expression-based than statement-based and eventually influenced the design of functional languages:
