@rhattersley Is it the hope that #116 will resolve:

>>> c = biggus.ConstantArray((2, 3, 4, 5))
>>> t = biggus.TransposedArray(c, (3, 1, 0, 2))
>>> print t
TransposedArray(<ConstantArray shape=(2, 3, 4, 5) dtype=dtype('float64')>, [3, 1, 0, 2])
>>> t[:2, 0, :, np.newaxis, :]
Traceback (most recent call last):

Yes. I've rebased the branch for #116 and I don't get that error any more.

With master:

>>> t[:2, 0, :, np.newaxis, :]
TransposedArray(<ConstantArray shape=(2, 4, 2, 1) dtype=dtype('float64')>, [2, 0, 3, 1])
