Ewww, kinda wish that would be an error... It would be too easy for a typo to get accepted this way.

In the latest version of numpy, this runs without an error, although may or may not be what you want:
|In [1]: np.array([[1,2],[[1,2],[3,4]]]) Out[1]: array([[1, 2], [list([1, 2]), list([3, 4])]], dtype=object) |
Here the result is a 2x2 array, where some elements are numbers and others are lists.
Specify the dtype explicitly: `dtype=int` or so, then NumPy will refuse to create a ragged array. There has been occasional discussion of `dtype='not-object'`, but I don't think it resulted in an issue or PR. Matti
