Closing b/c @landfillbaby has a better version.

oh ok i'll make a pr for mine then :)

@landfillbaby You can use Co-authored-by to share the credit if you want :)

[landfillbaby]

i think that's just for single commits, unless we squash them i think having your name on your commits is ok? i was originally planning on having you merge my changes into your branch and then that being merged into the original

@landfillbaby I assumed squashing the commits for a new PR would be cleaner. Either way is fine with me.
