What's the difference between sly-list-callers and sly-who-calls?

[Ambrevar]

I guess the same question applies to the difference between sly-calls-who and sly-list-callees, except that sly-calls-who seems to only work on LispWorks while sly-list-callees works anywhere.

• sly-calls-who should return a list of the functions that call the function named by the symbol.
• sly-list-callees should list all the call-sites of the function named by the symbol.

No,that's sly-who-calls. But you'd be forgiven for mixing it up, since the docstring in slynk-backend.lisp is broken, it is exactly the same for the two interfaces.

There are indeed two functions that do the same for every operations: callers or callees. The difference between the two inside each pair is where they gather information. As explained in slynk-backend.lisp, who-calls and calls-who use some implementations's xref mechanism (LispWorks and Allegro CL have one), whereas list-callers and list-callees use "lower-level grovelling". I don't know any more details. This was inherited straight from SLIME>

Thanks for explaining this!
