Two REPLs, post-scarcity on the left, SBCL on the right. In each, a recursive factorial function is defined, and the factorial of 20 is calculated. Both work. No one is in the least surprised that SBCL works.
The post-scarcity software environment does somewhat work, now. You can actually write functions and evaluate them. It's still very broken and I don't advise anyone to use it except as a curiosity, but it does somewhat work.

The people who created the official names for speech conditions clearly had a sense of humor and weren't afraid to poke fun at themselves! It's hilarious to think about the committee trying to come up with words like "dyslexia" and "lisp".

Interlisp has something "ugly" and "horrible": data for which READ is not an inverse of PRINT (ugly) or that cannot normally be dumped and loaded easily (horrible).

Nicolo Tartaglia should be the patron saint of #Lisp.
“Apparently the earliest work in which round parentheses are found is General trattato di numeri e misure by Nicolo Tartaglia (c. 1506-1557) in 1556.”

Two days ago, I had eight (out of one hundred and forty) unit tests failing, and I wasn't happy with my code. Last night, I had forty failing, and I thought things were improving. This morning I have one hundred and twenty four failing, so I *know* I'm on the right path!
#Software

[More Lisp semantics]
Modern #Lisp systems distinguish between several different types of string-like-things:
1. symbols
2. strings
3. keywords
By convention we typically use symbols as handles on things bound in the environment, keywords as handles on things bound in maps (hash tables), and […]
Screenshot of the black and white desktop of a 1980s graphical workstation environment. The desktop has a grey background pattern and some windows with a white background and a title bar with white text on a black background. The main window shows the online documentation of the Lisp function APPEND.
To consult the Medley Interlisp documentation execute MAN <query> at the Lisp prompt where <query> is the name of a Lisp function, form, topic, or library module. Try:

The core mechanics work. Phew. What a relief.
I am wondering what the best approach to the mini games will be. I think I will keep it simple. Every function for the mini games will have a similar structure, which would look like this:

#lisp #commonlisp #functionalprogramming
Woohoo! I just typed
`(mapcar (lambda (n) (:documentation (meta n))) (keys (oblist)))`
into the REPL of my frankenlisp, and printed out the documentation of every function it knows.
I am getting close to the point that other people can play with this...
#Lisp

In #CommonLisp, `=` takes arbitrary numbers of args, but `eq` takes exactly two.
In #Scheme `=` takes arbitrary numbers of args, and `eq?` also takes arbitrary numbers of args.
In #Logo, `equalp` takes exactly two args, and I don't think there's an equivalent of `eq` […]
