Duplicate of #29

Hi! Thanks for taking the time to contribute!

Because we treat issues as our backlog, we close duplicates to focus our work and not have to touch the same chunk of code for the same reason multiple times. This is also why we may mark something as duplicate that isn’t an exact duplicate but is closely related.

Thanks,
