"get_all_element" will only return the 1st item that would otherwise
be returned by "get_all_elements".
The "all" just means it works recursively.

So in your case, "get_all_element" should be returning a Block, which
itself contains some number of elements.

It's not very pretty - you have to dereference the array-ref to a
list, then count it in scalar context:

    $count = scalar @{ $form->get_all_elements({ type =>
Repeatable})->get_elements };

Hope that helps,
