A solution for the problem mentioned in #176 - that Clojure 1.10 added support for options in the
defprotocol
macro https://clojure.org/reference/protocols#_extend_via_metadata. Currently, the supported options are limited to:extend-via-metadata
, which adds two forms before the actual method definitions.This PR checks to see if the
:extend-via-metadata
key is present in thedefprotocol
body, and accounts for its presence or absence.
