Mmm, what does L stand for here?

541–545

std::any_of()?

Typo: "because".

Should we somehow indicate that we assumed that the function returns a success value? I.e., bug visitor / tag.

Also what is the intended behavior if we replace write_into_out_param_on_success with write_into_out_param_on_failure here?

That is, i really want this test added, and then it's good to commit, other nits are minor.

vaLue.
Other letters are usually taken =/ Is there a different convention ?

541–545

That's super verbose with iterators and requires putting those values in the array.
Unfortunately, libc++ does not have a

<template T, template Others...>
bool isAnyOf(T Val, Others... OtherVals)

function

L usually stands for Loc; V is more common for raw SVals.
