Thanks Warren, I think these are sensible additions.
I would argue to treat the None-False condition as an error. Indeed I agree
one might argue the correcr behavior is to 'shuffle' the singleton block of
data, which does nothing; but its more likely to come up as an unintended
error than as a

I like the suggested changes. Since
yeah, a shuffle function that does not shuffle indeed seems like a major
source of bugs to me.
Indeed one could argue that setting axis=None should suffice to give a
clear enough declaration of intent; though I wouldn't mind typing the extra
bit to ensure consistent semantics.

This is a maintenance release that fixes various bits and pieces.
Importantly, compatibility with Numpy 1.9 and Cython 0.21 has been fixed
and the test suit no longer segfaults on 32 bit UNIX.
Hi,
In part of my C++ code, I often do
void foo(PyObject * matrix) {
do stuff
}
where matrix is a numpy mxn matrix created on the Python side, where
foo() eg. is invoked as
a = numpy.array([[1,2],[3,5]])
foo(a)
However, if you call transpose() on a, some care should be taken, since
