I must admit though, I have never really gel'd with CLOS, or could never wrap my head around it entirely.
Abstract Vecto is a simplified interface to the powerful CL-VECTORS vector rasterization library. It presents a function-oriented interface similar to CL-PDF, but the results can be saved to a PNG instead of a PDF file. Since Vecto and all supporting libraries are written completely in Common Lisp, without depending on external non-Lisp libraries, it should work in any Common Lisp environment. Vec

I'd hardly call the 'back-enda' of sbcl or cmucl 'swiss cheese'. We don't know the cause of the problem we're encountering with deliverator on sbcl/cmu, or we'd have fixed it or gotten the sbcl devs to (depending on where the problem is), rather than assigning blame and switching platforms. The problem, in a nutshell, is that *something* isn't getting garbage collected despite the fact that we can
Why I Like CALL-WITH-* Style In Macros # hacking, June 6th 2007 One, fairly common, style of writing macros is to expand WITH-* into CALL-WITH-*: (defmacro with-foo ((foo) &body body) `(call-with-foo (lambda (,foo) ,@body))) (defun call-with-foo (function) (let (foo) (unwind-protect (funcall function (setf foo (get-foo))) (when foo (release-foo foo))))) There are several advantages to this, in com
