panic: Cannot range over: func(yield func(K, V) bool)

did you try updating Go and staticcheck to the latest version?

[feuGeneA]

I was already using the latest version of Go, but I had been using the version of staticcheck that's cited in the README. I updated to the latest staticcheck and it works great. I submitted a PR to update the README.
