Lisp early on exposes its dual nature of code and data. Even in interactive environments. This ever-present meta-level is unusual.

ECL and ABCL are Common Lisp implementations. They are both interactive and both don't use images. Unless one saves and load images, one is not using image-based development. All one is using is the interactive nature of Lisp, via a di

GNU Emacs wasn't written for Lisp. It was developed as an extensible text editor. Its extension language was also the implementation language for a large part of the software. Much of the application domain of GNU Emacs has nothing to

My basic mental model of SETF was always relatively simple. We were told that in university, many decades ago. Lisp has traditionally a bunch of different datastructures. Like cons cells with CAR and CDR accessors. RPLACA and RPLACD were th

The first Lisp implementation in 1960 already had function tracing.

It could be a helper-function which gets called by a macro expansion at compile-time. One would define the feature as a function which is available at compile-time and the macro calls it during expansion.

CLASP in C and C++ via LLVM. LispWorks and Allegro CL as shared libraries in various environments. LispWorks in iOS and Android Apps. SBCL, I think, now possibly works also as a shared library.

That's great that VB and Delphi had one in 97, but the Interface Builder for NeXT was released in 1988.

If you haven't seen it, the Interface Builder got its inspiration from this Interface Builder written in Lisp: https://vimeo.com/62618532 The version in the video actually ran on a TI MicroExplorer Lisp Machine NuBus

> SBCL is mediocre at best at optimizations but most people do say that. I would think that it takes a bit more knowledge to judge that. You'll need to understand a bit more how to declare types to achieve better results.
