Is `exists_one` getting renamed to `existsOne`?

It seems so in this PR, but I can find no evidence of a corresponding change to the spec.

You're very observant, thanks for bringing this up. I feel like exists_one was an accident since function syntax should be camelCase rather than snake_case. We'll retain support for both, though I will likely shift the documentation to existsOne once all implementations support the new macro name.

Would it be feasible to have a bleeding edge branch of the language spec where these things are specified ahead of code changes?
