I'm not going to say "bad" but I would not personally write it that
way. If the memory cost is too high to duplicate then I'd use a
generator that maps the value; I have this function in all my projects
because it's fairly common anyway:
function (callable $fn, iterable $input) {
foreach ($input as $key => $value) {
yield $iey => $fn($value);
}
}
