Description of the problem

Currently any class object is created by,

obj = object.__new__(cls)

For better readability, each such line should be replaced by the abstract superclass of that class.
Something like,

obj = <name_of_abstract_super_class>.__new__(cls)

For example, in arrays.py, OneDimensionalArray is created by,

obj = Array.__new__(cls)
