[eip-automerger]

Hi! I'm a bot, and I wanted to automerge your PR, but couldn't because of the following issue(s):

• File .codespell-whitelist is not an EIP
• EIP 107 requires approval from one of (@wighawag)
• EIP 1581 requires approval from one of (@bitgamma)
• EIP 1613 requires approval from one of (alex@tabookey.com, dror@tabookey.com, @yoav-tabookey)
• EIP 1930 requires approval from one of (@wighawag)
• EIP 2333 requires approval from one of (@CarlBeek)
• EIP 758 requires approval from one of (@tinybike)

This is needed to bring master back to operational state.

@nicksavers @Arachnid @Souptacular @gcolvin anyone wants to approve/merge?

As an author of 1193, I want to second @axic's call for merging this. We're at the end of our review period and need to get a final set of changes merged ASAP.

[Arachnid]

Can we please disable spellcheck as a required part of the build? It's absurd that a spelling error in one EIP can break the whole build - and since spell checkers have false positives, it shouldn't be required.

I'll chime in to say that the codespell check seems fine to me on paper so long as it doesn't prevent the repo from functioning normally. I'd be willing to help write docs for contributors on how to deal with it, but I'm not sure where to put them.

Also, we unfortunately seem to have missed one failure: #2691
