Common Lisp Koans is a language learning exercise in the same vein as the ruby koans, python koans and others. It is a port of the prior koans with some modifications to highlight lisp-specific features. Structured as ordered groups of broken unit tests, the project guides the learner progressively through many Common Lisp language features.

abcl has __ symbol defined in :cl-user

navoj opened this issue · comments

When I try to load contemplate.lsp with Armed Bear Common Lisp I get the error message that __ symbol is already defined in package :cl-user. I needed to move (use-package :lisp-unit) within (in-package :lisp-koans) in order to get things working. Does this break loading contemplate.lsp with sbcl, clisp, ccl, gcl?

Another problem I have found is that one of my quicklisp setups was conflicting with format.lsp. I don't know exactly what was causing that but disabling quicklisp in my .abclrc file fixed my lisp-koan setup.
