`mix dialyzer --format raw` output: ``` {:warn_matching, {'lib/braun_support/tracing/tracing.ex', 414}, {:pattern_match, ['pattern ', '']}} {:warn_matching, {'lib/braun_support/tracing/tracing.ex', 415}, {:pattern_match, ['pattern ', '']}} ```

@fabien0102 `ts-lint` is a typosquat version of `tslint`, stuck back at version 4.5.1 (cf 5.9.1). ~Not sure if it's safe or not.~ I'd switch. Update: I've confirmed `ts-lint` is a...
