ktn_code fails since ktn_dodger cannot parse macro functions in function clauses

Given the following module

-module(macros).
-define(MATCH_NAME(), #{name := "Per"}).
is_adult(?MATCH_NAME()) ->
    false.

Problem seems to reside in ktn_dodger:scan_form which does not send correct thing to erl_parse:parse_form.
