True. This argues against the MAH attributes.
However, I use transpose often when not dealing with linear algebra,
in particular with reading in data, and putting various columns into
variables. Also, occasional in plotting (which expects things in
'backward' order relative to x-y space), and communicating between
fortran programs (which typically use 'forward' order (x, y, z)) and
numpy (backward -- (z, x, y)).
I am very much in favor of .T, but it should be a full .transpose(),
not just swap the last two axes. I don't care so much for the others.
+1 for .T == .transpose()
