I'd like to point out that the numpy usage of the word "contiguous" is
a bit misleading: while naively one would expect it to mean that the
data were contiguous in memory, what it actually means is that they
are contiguous and the indexing is C-ordered:
In : a = arange(5)
In : a.flags["CONTIGUOUS"]
In : a[::-1].flags["CONTIGUOUS"]
In : eye(2).flags["CONTIGUOUS"]
In : transpose(eye(2)).flags["CONTIGUOUS"]
There's no help for it now, I suppose.
