The real question is:

Are you sure you need ITERATE? I.e., are you sure you couldn't just use LOOP?

Hello,

I just made available a little library that implements yet another^n DEFENUM in Common Lisp. Here is a link to the blog post: http://within-parens.blogspot.gr/2014/0 ... in-cl.html

Cheers and Happy New Year

Look at SHADOW and SHADOWING-IMPORT.

With care and understanding that C++ "hiding rules" are not the same as CL. Plus, and this is the biggie, methods (or "member functions" in C++) are *NOT* part of a class definition. CLOS classes are essentially "data only classes" (something that some SW engineer does ...

Your spec is not complete. Why do you want to keep (A B C) only? Do you want to keep the first? Do you want to keep all the (A B C)? Do you want to remove only the duplicates of length other than 3? Assuming you want to keep all entries of length equal 3, here is a solution that should give you a hi...

Sure.

BTW. Your version behaves more like (SETF GETHASH). It's a design choice.

Using GETHASH does not change the basic issue. The easy solution is to use a SEFT definition (defun (setf cadsoc) (v key alist) (let ((kv (assoc key alist))) (if kv (setf (cdr kv) v) (error "Key ~S not found in a-list." key)))) Now you can do: CL-USER 2 > (defvar l (acons 42 'a ())) L CL-U...

People pointed out that some git repositories of mine on common-lisp.net were not clonable. I fixed the problem and now you should be able to clone the repositories for NEW-OP (http://common-lisp.net/project/new-op) and XHTMΛ (http://common-lisp.net/project/xhtmlambda)

You can do whatever you want as long as it makes sense (TM) YMMV, etc etc.

Having said that, I came to like the one-class one-file organization of Java. Alas, with multimethods and generic functions there isn't a natural breakdown like that in CL.

It depends on the kind of code you are producing with a macro.
