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 this makes simple linear algebra computations more difficult.
I propose adding an argument to transpose, perhaps called `expand` or `expanddim`, which if `True` (it is `False` by default) will force the array to be at least 2D. A shortcut property, `ndarray.T2`, would be the same as `ndarray.transpose(True)`.
