instance method

Enumerator#each_with_index

e.each_with_index {|(*args), idx| ... }

e.each_with_index

static VALUE
enumerator_each_with_index(VALUE obj)
{
    return enumerator_with_index(0, NULL, obj);
}

Same as Enumerator#with_index(0), i.e. there is no starting offset.

If no block is given, a new Enumerator is returned that includes the index.
