Silly question:

I've noticed now that when starting up SLIME + SBCL that there is some functionality that is seemingly not provided:

WARNING: These Swank interfaces are unimplemented: (CALLS-WHO DISASSEMBLE-FRAME SLDB-BREAK-AT-START SLDB-BREAK-ON-RETURN WHO-SPECIALIZES)

My question is what Lisp implementations do support various options and features of SWANK. It might be nice to have a compatibility matrix or something on the front page, as I think knowing who-supports-what in SWANK could be of great importance to some.

In particular, the most important one that is paining me a tiny bit by its absence is CALLS-WHO.

Thanks, df
