Funnily enough you already show how this can currently be done.
My point would be to make simple things simple and keep complicated
things possible. As it is right now.
So I'd use
array_map(function($p) {return $p->age;}, $people);
or
usort($a, function($a, $b) { return strcmp($a->lastname, $b->lastname);
});
to do Stefan Walk's example.
But something like your pick function using create_function if I
*really* wanted something more fancy.
