[Numpy-discussion] immutable numpy arrays

2008-12-17 Thread Geoffrey Irving
Currently numpy arrays are either writable or unwritable, but unwritable arrays can still be changed through other copies. This means that when a numpy array is passed into an interface that requires immutability for safety reasons, a copy always has to be made. One way around this would be to ad
