"""
This module provides a selftest for the numarray.memory c-extension.
>>> m = new_memory(10)
>>> len(m)
10
>>> for i in range(len(m)):
... m[i] = i
>>> str(m)
'\\x00\\x01\\x02\\x03\\x04\\x05\\x06\\x07\\x08\\t'
>>> [ x for x in m ]
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> [ x for x in m.copy()]
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
A slice of a memory object returns an alias to the sliced region, not a copy.
>>> str(m[5:8])
'\\x05\\x06\\x07'
>>> m[5:8].tolist()
[5, 6, 7]
>>> m[5:8] = [20, 30, 40]
>>> m.tolist()
[0, 1, 2, 3, 4, 20, 30, 40, 8, 9]
>>> n = new_memory(10)
>>> o = new_memory(3)
>>> n.clear()
>>> for i in range(len(o)):
... o[i] = 10
>>> n[2:5] = o
>>> n.tolist()
