Comments for Irreal http://irreal.org/blog The minds had long ago come up with a proper name for it; they called it the Irreal, but they thought of it as Infinite Fun. That was what they really knew it as. The Land of Infinite Fun. --Iain M.

Desperately trying to think of a use for it now. :) That’s great fun. Desperately trying to think of a use for it now. :)

I mainly use GNU Guile on GNU/Linux (debian). The most confusing part of scheme was different implementations having different module systems! This totally removes any portability between systems (as you state when moving from Dr Racket to Guile). Over the past 2 years I have been getting into scheme.

There are several POSIX things the CL standard never addressed: http://rosettacode.org/wiki/Scripted_Main#Common_Lisp Scheme may not always carry across, but the SRFI library calls do. Have you tried Chicken Scheme? It's as practical as Python, but more lambda-y. http://call-cc.org/ Just try doing shebang lines. There are several POSIX things the CL standard never addressed:

I use exactly the same formulas, but computed the differences at each step, this allows for bigger numbers without overflowing. It also is pure elisp. It uses recursion, so I don't know if it still O(n), the FOR equivalent would be, but recursion feels more "lisp".

I had used both a greater than and a less than symbol but now the text between the two is deleted, even though I used a <code>code</code> tag. I'll leave the missing code as an exercise for the reader. Commenting is broken.
