Description:
------------
Would it be possible if ReflectionMethod and ReflectionFunction's getClosure() methods always returned the same Closure object? e.g:

class Foo{ function bar(){} }
$a = new ReflectionMethod('Foo', 'bar');
$b = new ReflectionMethod('Foo', 'bar');
$foo = new Foo();
$aa = $a->getClosure($foo);
$bb = $b->getClosure($foo);
assert($aa == $bb);
assert($aa === $bb);

Object that would have the same lifetime of the object the variable $this is set to ($foo, in previous example). It would be nice if we were allowed to use === operator for comparison. Similarly

$aa = $a->getClosure($foo)->bindTo($foo, 'static');
$bb = $b->getClosure($foo)->bindTo($foo, 'static');
assert($aa == $bb);
assert($aa === $bb);

might also be valid, but I imagine this would complicate things enormously.

Thank you in advance.
