I haven't seen such a function in the "draft" standard I have found.
It seems it is not yet available from INCITS.
There are also EVERY (= aggregate AND) and SOME/ANY (= aggregate OR) for
booleans, that are interesting. I'll add them with the patch. However I
think that I may need to add two small functions for that.
