I would make `arr.T2` the same as `np.atleast_2d(arr).T`. So a 1D array
would act as a row vector, since that is already the convention for
coercing 1D arrays to 2D.

When you try to transpose a 1D array, it does nothing. This is the correct
behavior, since it transposing a 1D array is meaningless. However, this
can often lead to unexpected errors since this is rarely what you want.
You can convert the array to 2D, using `np.atleast_2d` or `arr[None]`, but
