It think it would be a real shame not to support non-contiguous data.
It would be great if such a byte object could be used instead of
Numeric/numarray arrays when writing extensions. Then I could write C
extensions that could be made available very easily/efficiently to any
package supporting it without having to worry about the specific C api
of those packages. If only contiguous byte objects are supported that
byte object is not a good option anymore for implementing extensions
for Numeric unless I am prepared to live with a lot of copying of
