They did not run Lisp as machine code. They either ran a machine code, which Lisp was compiled to, and/or they ran a Lisp interpreter, which ran Lisp source code. The machine often was kind of a stack machine, with microcode implementi

GNU Emacs has complex code to deal with it. Some "ls" programs support a "-dired" option, some not. If this option is not supported, then Dired may fail to parse some unusual filenames. Then there is an 'ls' em

This interactive introspection is usually facilitated by dynamic types and actual types in the software. For example large parts of the Lisp software in the 80s were already written in an object-oriented way, where the code was structured

Maybe because the language is not untyped? It has both dynamic typing and optional static typing.

No, the differences is that in Common Lisp / SBCL type declarations are optional (note though: there is also type inference in SBCL), type declaration are more verbose, type declarations are sometimes a separate expression and a vari

I would think that there are many dialects, but they share a common core. Common Lisp is just one. Others would be Emacs Lisp, Visual Lisp, Interlisp, Standard Lisp, ISLisp (which is an ISO standardized Lisp). Something like Janet is furthe

The functional Lisp (Lisp without assignment) was called "Pure Lisp" back then. Sometimes also there was the term "applicative language".

CLASP may be newer, but it is hardly more 'modern'. There is only limited adoption of CLASP in the Lisp community, because its advantage (excellent integration into C++) is only interesting for a small group of users. At the same

why would one implement Common Lisp in Rust? Most implementations are largely written in Common Lisp itself, plus some runtime (memory management, threads, OS interface, ...) underneath. The runtime can be specially written in C (maybe Rust
