Hi,
Julian noted that C-c C-k doesn't work (well, it does, but it doesn't DWIM) in sbcl source files. Attached is an abstraction-violating patch that makes it DWIM... as ever, I'm unsure of how best to remove the violation of abstraction boundaries. (And whether the way I've violated the abstractions is the right way, come to that).
Cheers,
Christophe
