static function from(string|int $value): static

$value	string \| int
returns	static

static function FromString(string $value, bool $throw = true): ?self

$value	string	a `$xxx` mongo-style name, or a shorthand alias (e.g. '&', '\|', '!')
$throw = true	bool	if false, return null instead of throwing for an unrecognized $value
returns	null \| self

GroupOperator::FromString('|'); // GroupOperator::Or

function test(callable $test, ...$args): bool

$test	callable	function(mixed $member): bool -- called on each of $args in turn
...$args
returns	bool	NOTE: an empty $args list always returns true for every operator (AND/OR/NOR alike): no members means no constraint, not "nothing can match"

GroupOperator::Or->test(fn($v) => $v > 0, -1, 2, -3); // true: at least one member (2) passes

static function tryFrom(string|int $value): ?static

$value	string \| int
returns	null \| static
