I've found this feature quite useful in the couple of days since I implemented it. Thought it might be worth posting it to the list in case it's useful for others too.

The feature adds slime commands (un)trace-package, with menu entries under "Debugging". These commands (un)trace all fbound symbols in the named package, which defaults to (slime-current-package).

Attached is a diff against current cvs slime. It works for me with a recent cvs emacs and sbcl.

Cheers, Bill.
