Nativity #Forth is now self-hosting. Here is the Forth source of the assembler that bootstraps it. The binary size of the assembler is 2 KB. That is 1/1000 the size of Hello World in Rust.

Not having POSTPONE or CREATE-DOES implemented, I always have to think very hard whenever I write a #forth defining-word. Anyway, here's MARKER. For those unfamiliar, it saves the current extent of the Forth dictionary so it can be restored later, discarding any data that was appended in the meantime. It works by defining a new word of user-specified name that, when invoked, restores the saved

Progress disassembling MuLISP is much faster than Turbo Pascal. However there are some copies and an indirect jump that I haven't been able to follow yet. #reverseengineering

Meanwhile, in a traditional 1960s or 1970s Lisp you would use FUNCTION, which would implement a FUNARG device that closes over the dynamic environment. However, I can't find a vintage environment offhand that lets me demonstrate this. Medley Interlisp-D seems to have dropped support at some point!
(BTW, in the Interlisp version of FUNCTION, it appears you still must specify a list of variables t

I suppose this means other people now can edit the language core without a warez copy of Borland Turbo Assembler from the late 80s... lol. I have a licensed copy and it never occurred to me that not everyone does.
In case anyone wants to look at the gnarly assembly dialect that my 2K assembler takes: https://gitlab.cs.washington.edu/fidelp/nativity-forth/-/blob/master/CORE.4SM

Aha! If you can arrange for the "closures" to share structure, then you'll have the equivalent of "multiple functions closed over the same environment". Again in muLISP:(let ((alist '(quote ((x . 1)))))
