Missing clause bug - Githubissues

Hi,

I actually have an issue with Dogma on last elixir release (1.8.1) running on Erlang/OTP 21.

** (CaseClauseError) no case clause matching: {:ok, [{:identifier, {1, 1, nil}, :defmodule}, {:alias, {1, 11, nil}, :Dogma}, {:., {1, 16, nil}}, {:alias, {1, 17, nil}, :RulesRunBench}, {:do, {1, 31, nil}}, {:eol, {1, 33, 1}}
, {:identifier, {2, 3, nil}, :use}, {:alias, {2, 7, nil}, :Benchfella}, {:eol, {2, 17, 2}}, {:identifier, {4, 3, nil}, :alias}, {:alias, {4, 9, nil}, :Dogma}, {:., {4, 14, nil}}, {:alias, {4, 15, nil}, :Rules}, {:eol, {4, 20
, 1}}, {:identifier, {5, 3, nil}, :alias}, {:alias, {5, 9, nil}, :Dogma}, {:., {5, 14, nil}}, {:alias, {5, 15, nil}, :ScriptSources}, {:eol, {5, 28, 2}}, {:at_op, {7, 3, nil}, :@}, {:identifier, {7, 4, nil}, :sample_script_p
ath}, {:bin_string, {7, 23, nil}, [""]}, {:eol, {7, 25, 2}}, {:identifier, {9, 3, nil}, :bench}, {:bin_string, {9, 9, nil}, ["1 file"]}, {:",", {9, 17, 0}}, {:"[", {9, 19, nil}}, {:kw_identifier, {9, 20, nil}, :scripts}, {:p
aren_identifier, {9, 29, nil}, :get_scripts}, {:"(", {9, 40, nil}}, {:int, {9, 41, 1}, '1'}, {:")", {9, 42, nil}}, {:"]", {9, 43, nil}}, {:do, {9, 45, nil}}, {:eol, {9, 47, 1}}, {:identifier, {10, 5, nil}, :scripts}, {:arrow
_op, {10, 13, nil}, :|>}, {:identifier, {10, 16, nil}, :run}, {:eol, {10, 19, 1}}, {:end, {11, 3, nil}}, {:eol, {11, 6, 2}}, {:identifier, {13, 3, nil}, :bench}, {:bin_string, {13, 9, nil}, ["5 files"]}, {:",", {13, 18, ...}
}, {:"[", {13, ...}}, {:kw_identifier, {...}, ...}, {:paren_identifier, ...}, {...}, ...]}

This impact two files, the first one is lib/dogma/script.ex and we should a new pattern matching. The other one is present in lib/dogma/rule/infix_operator_padding.ex. This last one crash with this tuple:

{:sigil, {24, 10, nil}, 83, ["no-op with =~"], [], "{"}}

It seems that last elixir version add a new way to answer with tokens (a longer tuple). I made this patch with a small test. Please tell me if you are agree with this patch and/or you have same issues on your side.
