Ever got those annoying "Protocol String.Chars not implemented for GIANT BLOB OF DATA" errors in #ElixirLang ??

I just sent a PR to make that much nicer 😎

Fun fact, in #ElixirLang 1.20, there's a new `mix test` flag: `--dry-run`. It should help you when making large changes to a test suite, like version upgrades!

Try it out: `mix test --warnings-as-errors --dry-run`
