Instance Public methods
Converts any arguments to arrays, then merges elements of self
with corresponding elements from each argument.
This generates a sequence of ary.size n-element
arrays, where n is one more than the count of arguments.
If the size of any argument is less than the size of the initial array,
nil values are supplied.
If a block is given, it is invoked for each output array,
otherwise an array of arrays is returned.
