The patch contains a few tests to verify that it does not completely break the compiler, but not a complete test-suite for the new functionality. Current Slime needs a one line patch to enable arglist display for the patched ABCL; I've included this patch as well.
Thanks for the patch, I'll be applying it shortly.
The tests don't seem to have the Classpath exception (neither do the existing ones), I guess that's intentional. Just something I noticed. That's fine, so no actions necessary.
