Array of Arrays

1D Array

arr = []int(1,2,3)

2D Array

[][]T(...) translates to a variable sized vector of vectors. None is allowed as a sub-vector because each sub-vector is wrapped by std::shared_ptr. Array comprehensions can be used in the constructor as sub-vectors. https://github.com/rusthon/Rusthon/blob/master/regtests/c%2B%2B/array_of_arrays.py

	arr = [][]int(
		(1,2,3),
		(4,5,6,7,8),
		None,
		(x for x in range(20)),
	)

TODO Objects None can be used in the sub-vector in place of an A instance.
