[Numpy-discussion] _contiguous A trap for the unwary

[Colin J. Williams]

The assignment of a value to self._shape has an unexpected side-effect.

self.iscontiguous() changes from True to False     -  desirable, but 
unexpected
self._contiguous remains with the value 2.

I had expected _contiguous to be in step with iscontiguous().

How does the function iscontiguous() determine contiguity?
Is the variable now redundant?
