Hi,

Happy new year to everyone.

I would like feedback on idea to add stream api to ArrayObject, something
like array_map and array_filter.

Consider following example

$students =3D new ArrayObject();
//...
$bestStudents =3D new ArrayObject();

foreach($students as $student){
if ($student->grade() > 4) {
$bestStudents[] =3D $student;
}
}

And example with Stream API.

$bestStudents =3D $students->filter(
function($student){
if ($student->grade() > 4)
return true;
}
)->map(
function($student) {
return "{$student->firstName()} {$student->lastName()}";
}
);

I gave example only with map() and filter(), but there are also couple of
others functions which could end up here.

Cheers,
