#programming #engineering #mathematics #commonLisp ellipse drawing article drastic improvement. A walkthrough to using cl-series #series macro package.

Now in the old one yesterday (I was coming down with a cold!) I got the somewhat cutting feedback "should've been 6 lines of #python ". Honestly, pythonistas, I am ready to learn what you have to teach ;p.
Thoughts, feedback, criticism most welcome. What's /your/ example?

@vnikolov Yeah, cause it is totally backwards. Masinter had nothing to do with #CommonLisp LOOP (which was done "I suppose" by William Lott -- it was a rewrite of the original LOOP for MACLISP / Lisp Machine -- that also ran on Common Lisp). LOOP for the CL standardization process was by Jon L White, but earlier records are unclear -- it drew inspiration from CLISP in Interlisp; but was not compatible.

Oh, I've probably got it complete wrong again. I was meaning to go back and transcribe that interview anyway. We were both very tired at the time.

That would definitely be a Good Thing.

So months and months ago, without me having turned up to the interlisp meetings since (I was busy!) and hence probably much to his chagrin, I interviewed Masinter who clarified that common lisp's loop was more or less the one he wrote for lisp360 [] unless I have become confused and imagined that into existence!

It seems to me we might be thinking here of the Lisp Machine and then of Symbolics 3600.
By the way, I had the impression that JonL wrote the `loop' macro, but by all means check that.

I guess the big lisp360 loop at the front alienates half the people, and the series::install alienates the other half ;p

And the third half view it in a rational way 🙂.
Just a coincidence, but I think you might trademark "lisp360" or "L/360" as a hybrid of lisp machine and S/360 🙂.

For what it's worth, that had been exactly how I had understood it from the beginning.
As to how historic or historical each of the above-mentioned is, I'm not the judge of that 🙂.

I know some people have also pointed out that me sharing this will be confused with common lisp CLIM spec / McCLIM, scigraph, Maxima, Macsyma, etcetera etcetera which are historic and historic in the sense of being famously good. I will do articles on those /later/. This one was my attempt to demonstrate series useage.

@vnikolov @screwlisp The earliest record I have is parts of a manual for LOOP (LIBDOC; LOOP 61, March 6th, 1980) -- but it has no author.

[Origins of LOOP in #CommonLisp?]
Thank you.
Kent, would you happen to have anything on the authorship of the `loop' macro within easy reach?
Alfred M. Szmidt
@vnikolov @kentpitman @screwlisp And Alan Bawden I think maintained the MIT LOOP for quite some time.
