Consider issuing warnings for multiple Clojure symbol names that map to same strings after munge

[jafingerhut]

Excerpts from a conversation on Clojurians Slack channel #clojure-dev on 2018-Sep-05:

"I had an issue where I had two functions in a file, replace-_ and replace_-. This worked in dev, but when I aot the project, any invocation of either is replaced by the last one in the file. I suppose this is because munge gives the same result for both those names."

"The clojure names of the fns are foo.common.core/replace-_ (and replace_-). The class in the jar is /foo/common/core$replace__.class"

Eastwood already issues a warning when def'ing the same name twice. A new check could be implemented as a variation of that one. If so, it would probably be best to name it differently than the current one, so they could be turned on/off independently of each other.
