On the other hand, by his description, he wants to create a function that like butlast, but with reversed order of arguments.

You shouldn't do like this: (defun suffix (x &rest args) (setf f 0) ...) First, you want to pass only 2 arguments to the function suffix. In you example, (suffix 3 '(a b c d e f)), the first argument is 3 and the second is '(a b c d e f). In this case, you don't need the &rest directive. Sec...

Function calls in Lisp are done this way: (f a b) - calls f with a and b as arguments. In C you would write f(a,b), but in Lisp you put the function being called inside the parentesis as well.

A quick search into http://www.cl-user.net/ gave me the following results: http://common-lisp.net/project/cl-mathstats/ http://nlisp.info/ http://matlisp.sourceforge.net/ http://common-lisp.net/project/gsll/ http://aleph0.info/spartns/ (for sparse vectors / matrices) Anyway, it doesn't hurt to progr...

Have you seen Lispbuilder-SDL? It is an interesting alternative, at least 4 games were created using it and it is pretty much stable.

Just to mention, you can check lispbuilder at sourceforge, but it is outdated. The first link is better.

Indeed, defining compiler macros for standard functions is classified by the ANSI as "unportable code". But reduce does accept a key argument, so:

Not all "interpreters" are written in C/C++. And we don't usually say "interpreters" because most implementations (maybe all of them?) compiles the code, sometimes to C code, sometimes to bytecode, or even directly to assembly. If you want to see the C / C++ source code of an imp...

Reducing in place? Ok:
what about this, then:
?

Mudballs, as much as I understand, is a replacement for ASDF, not only ASDF-install. I have nothing against it, but I don't have any reasons to abandon ASDF itself, and almost all projects already use ASDF, which means everyone have it already installed and configured. The combination clbuild+asdf s...

I use clbuild, it can update everything in an easy way - you ask for updating a lib, it updates all of it's dependencies, just like a package manager. I don't think shipping dependencies together is the best answer anyway, but the problem is asdf-install.
