xref navigation of Clojure methods

(Feature request)

It would be good to have a way of viewing and navigating to all the methods for a multimethod.

Two things I've seen before (in LispWorks for Common Lisp) are:

- After M-. shows a multimethod, another command can be invoked repeatedly to navigate to each of the methods.
- Something that lists all the methods for a multimethod and supports navigation to a chosen method (perhaps a sequence to cycle through in the minibuffer, perhaps an "inspector" buffer) .
