Description

user=> (source clojure.core.protocols/coll-reduce)
Source not found

But since the protocol fn's var's metadata points to the protocol var, and the protocol var knows the file and line where it was defined, it would be trivial to improve 'source' to look like this:

user=> (source clojure.core.protocols/coll-reduce)
(defprotocol CollReduce
  "Protocol for collection types that can implement reduce faster than
  first/next recursion. Called by clojure.core/reduce. Baseline
  implementation defined in terms of Iterable."
  (coll-reduce [coll f] [coll f val]))
