(let ((a 10) (b 20) c) (declare (type (integer 0 *) a b c)) (setf c (* a b)) c) Above is a LET expression, a variant of a lambda application. It does not look like a function call. It looks like an operator list form, wi

> By contrast in a lisp the syntax for setting a variable looks the same as the syntax for looping and for everything else. It's all just function calls. Not really. Setting a variable in Lisp is not a function call. IF is also not

by lispm 2y ago
Strange, the Lisp example has a lot of syntax, even though the article claims it hasn't. letrec, lambda, or & and are not functions in Scheme.

I don't think that Emacs Lisp needs to be a "full Lisp", whatever that would be, but it would need, for example, some improvements in the structuring of large programs, since there is now a lot, and still growing, amount of c

Obviously you are wrong, since it has been already demonstrated that it's not useless, as already the GNU Emacs example shows. It comes with a lot useful and well written software -> in Emacs Lisp -> roughly 1.5 million lines of

Where does the DEFCLASS stuff originally come from? Is it documented somewhere? As I understand it is from before Flavors? Flavors then replaced it or is there some deeper relationship?

One of the downsides is that implementations like SBCL have a deep integration and need things like a well performing GC implementation - to get this running on specialized game hardware is challenging. The article describes that. Getting o

Definitely. Interlisp and Smalltalk were early on mostly driven by research (Interlisp -> everything AI, Smalltalk -> UI research, OOP, AI) and specific early applications. The Mac UI was early on more direct manipulation oriented. On

Probably. They may have seen such a machine. But both the LISA and the Mac were very different from UI, Software and Hardware. Steve Jobs vision was eventually to get to the Dynabook (-> MacBook, iPad). LISA and the early Mac were steppi

And all that is independent of the PERQ. The article states (and it makes sense) that the PERQ had influence on the modern Mac, the Macs running Mac OS X and later. Since NeXT and then Apple used UNIX on a Mach Kernel, the latter came as a
