Recent experience shows that changes leading to ASDF 3 have changed the way one must specify new operation classes, in a way that is not backward-compatible. Thanks to Faré for helping me diagnose problems in one such system.
I will be looking into this, and hope to add at least one new test to ensure that we are probing this important aspect of ASDF going forward.
Related to this, does anyone have a good sense of which quicklisp systems might contain new operation and component classes?
thanks, R
