Hey @newAM , thank you for the PR!

I think CommonLang can either be removed entirely (my preference, from a quick glance shouldn't be used anywhere anyways) or annotated with an allow(dead_deadcode) exception. I don't think the current approach is the right way.

@matthiasbeyer I don't think we're aligned on the quality bar for cargo-spellcheck :)

Sounds good, I removed the CommonLang type!
