The LOOPS primer, published in 1987, captured well the essence of exploratory programming in Lisp:

The LOOPS interface provides both a programming tool and a thinking tool. As you develop a new system, each preliminary version provides an object for thought and discussion. The preliminary versions are a crucial part of the design process.

LOOPS (Lisp Object-Oriented Programming System) is the OOP extension of Interlisp.

@screwlisp indeed. But Medley is also not a pure InterLisp, and it lost something very significant in the change – namely, the structure editor. It cannot be impossible to add the structure editor back in, and by now someone must have done it. But for people used to InterLisp, and especially for me having come from Portable Standard Lisp, that was a very big loss.

Using a text editor to edit #Lisp still feels Just Wrong.

No Edrx (https://anggtwu.net/) again, but I will read a note from him about his own type theory quest.

He speaks to some of the different meanings that appear when different people say the words type theory, as appear on the Mastodon recently!

Also, I got a lot of notes on obvious improvements and contex for my https://screwlisp.small-web.org/ articles so far which we can share and talk about!
