A society determines which harmful substances (and its effects on the individual and the society) it tolerates and how. Alcohol is in Germany tolerated (more than in the US) and it is also a huge legal business. I'm for tolerating both

Evaluating conditions don't introduce bindings in COND. In Lisp typically bindings are only introduced in forms together with scope: DEFUN, LET, and a lot of other constructs. Binding construct which affect forms outside its syntactic

Scope of the bindings is the problem, not the bindings itself.

But with an effort to be backwarts (sic!) compatible. Code moved from Maclisp to ZetaLisp to Common Lisp. One can write (mapcar (function (lambda (...) ...)) ...), but the (dolist (...) ...) is still there. Even PROG is still there. For Sch

Let's assume they had 10 times the people and something between 5 to 20 times the code size. Going from 100 to 1000 people adds a lot complexity. I would think that adding good and experienced managers is important. Keeping all these p

One can absolutely work in groups using Lisp. There are a lot of examples for that. Often the groups don't need to be that large when working in Lisp. Code in larger projects tends to be more compact. I heard for example of 1/10th

The difference has not been "provided by me", the discussion around Lisp family vs. dialects goes on for several decades. We had the same discussions on comp.lang.lisp decades ago, while Scheme users then had their own comp.lang.s

Lisp usually means a Lisp which identifies as such: Common Lisp, Emacs Lisp, ISLisp (which is an ISO Standard), Emacs Lisp, AutoLisp, Interlisp, ... Languages like Scheme have their own standards (RNRS, IEEE Scheme, SRFI, ...). It's pe

Sure it is a lot. It is extremely much. Your mistake is to compare it to the US. The US spends more, but for its world-wide empire, much of which has nothing to do with defending Europe or even NATO. That's not what Europe needs do.

by lispm 3y ago
The funding is less of a problem. European countries spend a lot. It's just very diverse. The US has one army and one commander. Europe has 20+ armies and as much commanders. Around 250 billion a year is for example a lot more than wha

Paging would be another option. Virtual memory was slow and the GC integration with virtual memory wasn't very sophisticated at that time. Also main memory was probably tiny.

They also had "relatively large main memories" ;-) "(~1 megabyte) and virtual address spaces (4-16M 16 bit words)". I would guess the CPU speed would be rated less than 1 MIPS.

SLIME for Lisp exists since a long time. It has a server component. From what SLIME provides, one can see that the functionality used for interactive Lisp programming is different what one would use for many other languages. One is not comm

One of the main differences is that much of Mathematica is written in C++ (for example the UI). The Mathematica language then itself is a slow language (term rewriting, is not a really good low-level language). Medley is written is largely

Reducing indentation is mostly a non-goal in Lisp. Can't work with nested lists? Don't use Lisp. Lisp processes nested lists. Lisp means List Processor. You may want to do it in a text oriented language, but not so much in an expr

Lisp is not "line oriented", but "expression oriented". Lisp is a "List Processor", not a "Text Processor". If you want to group expressions in a REPL into one expression, use PROGN (or similar). The

Programming languages may let you define variables by assigning them. But the scope can differ across languages. Common Lisp requires one to clearly define the scope. PROGN does not create a scope. > Why does LET even exist as an alterna
