Hello everyone, My name is Justin and I am a freshman at Worcester Polytechnic Institute in Massachusetts. I discovered Concatenative languages perhaps a year...
Hi there, First, I'm glad to read that kind of post, very suited for FP newbies like me. I wonder if the Concatenative group has knowledge of the Forth effort...
... As far as I know, Dijkstra didn't have a beef with recursion. The author of the following retrospective writes that Dijkstra probably considered recursion...
... Knuth seemed to see more use for it than that. But I grant your point, and I wouldn't want to be _against_ Dijkstra on any point, anyhow. ... That feels...
... It seems to me from _A Discipline of Programming_ that he thought recursion a special case, relatively unimportant: the programming language he introduces...
... True, but that doesn't matter: you translate the conditional GO into a conditional invocation of the function corresponding to the labeled code. ... In a...
... But he mentions recursion favorably in the letter you were using to indict it. I'm confused. ... By "mess" you mean obfuscated and unintelligible? I...
... I don't know the term "lambda-lift", and Google knows of it mainly as a bunch of source files (I did find a 1985 paper on the topic, but it's a little...
... I'll reply to both of your messages in one. ... Then the analysis difficulty (if there is any) is obviously in the shuffle, not in the tail-call. The...
