pow is part of #4125 !

Will merge tomorrow unless I get feedback.

Thank you for spotting though!

[max-sixty]

Will close since #4125 is merged. Thank you regardless!

@max-sixty I'm not sure of the state of this, but the table of Operator Precedence (https://prql-lang.org/book/reference/syntax/operators.html#operator-precedence) in the public Book is still messed up. Would you check? Thanks

[max-sixty]

Yes, we should do a release. (Generally we push docs-only changes to web, but here it was both docs and code...)

In retrospect I should have merged yours, backported to web, and then resolved the conflicts with mine. Sorry!

[richb-hanover]

Ahah! I see now... Both code and docs. I shoulda made separate PRs. I'll do that next time... Thanks

Yours was perfect! Because this was docs only. So mea culpa...

I don't do "blame". It's enough if it gets fixed when it's pointed out. See WPNTFIIWDKIB
