ArrayIterator and `for` loop

[mruz]

I have simple Arr helper with getIterator() method:

class Arr implements \ArrayAccess, \Countable, \IteratorAggregate
{

    protected _data = [] { get };

    public function getIterator()
    {
        return new \ArrayIterator(this->_data);
    }
    //...

Is it possible to ArrayIterator work with for loop?

let tokens = new Arr([1,2,3]);

for token in tokens {
    var_dump(token);
}

The argument is not initialized or iterable()

So I must use:

for token in tokens->getData() {
    var_dump(token);
}

This way:

for token in iterator(tokens) {
    var_dump(token);
}

Thanks, I didn't know about the forum.

Could Zephir auto-detect if object have getIterator() method? What do you think?

You mean at compile time or runtime?

At compile time, before error check if argument has iterator.
