I recently installed SBCL (MS Windows not Cygwin), Emacs (MS Windows not Cygwin), Slime, and Quicklisp. The problem is Quicklisp; when I first installed it everything was okay until: (ql:add-to-init-file) Which failed and froze the REPL! I realized there wasn't a .sbclrc file so I created it, and tr...

Hey, Goheeca! I've been using Cygwin on Windows 7, (don't laugh), for development which doesn't have a port for SBCL . So I went to their site, downloaded the x86 installer, ran it, started SBCL , evaluated *features* and there was absolutely no thread package! So a quick search turned up: Threads a...

The reason is that Common Lisp functions do not handle multiple values by default. Multiple values are explained here: Practical Common Lisp , Chapter 20, Section Multiple Values Common Lisp, the Language, 2nd Edition [CLtL2], Section 7.10.1 Constructs for Handling Multiple Values CLtL2 is older th...

Sorry, but it's not really clear what you mean. If you want to use #'* with multiple values then use MULTIPLE-VALUE-CALL : (multiple-value-call #'* (values 3 4)) => 12 If you want to replace VALUES by a different function then you could use APPLY and LIST : (apply #'* (list 3 4)) => 12 Is this what...

Hey,
is there a function like values that would allow me to do this?
Thanks.

VIELEN DANK! . I had noticed in the stepper that there appeared to be only (2) applications were occurring, (for the 'b and 'm lambda functions). I was thinking of adding another funcall, then I saw your reply. I haven't been well of late, so please bear with my shortcomings for now. Again, thanks.

Thanks for the reply... I learned most of what you posted when I started learning about closures, but hey, since I'm still a n00b, better sage than sorry. I had to look at the situation for myself and realized that I had to approach the problem in pieces. On the webpage I posted above: (defun smalle...

Greets. I'm having a problem understanding nested lambda expressions. In particular, the example I've banged my head on: (λ(a b)(λ(m)(m a b))) ;; Where m is a function So ... ((λ(a b)(λ(m)(funcall m a b))#'*) 3 5) ;; returns => #<SYSTEM-FUNCTION *>in clisp/emacs/slime The only thing I was able t...

A tail recursive solution (but it still needs help with TCO from the implementation not to blow the stack) Since all the structure is made within the function it's safe to do du destructive reverse. (defun dotted-list (lst) (labels ((aux (lst i acc) (if lst (aux (cdr lst) (1+ i) (cons (cons (car ls...
