Rather than introduce a new kind of iteration mechanism, how about
just creating a library in userspace which provides a proxy interface:
class Reader implements Iterator {
protected $it;
public function __construct(iterable $it) { $this->it = $it; }
public function current/key/next/rewind/valid() {
$this->it->current/key/next/rewind/valid(); }
public function read() { /* What a reader should be */ }
}
Then you can use any already extant iterable via: $reader = new
Reader($iterable);
This could live in a composer/packagist library and work on already
released versions of PHP.
Or is there something I'm missing?
