Description

When creating an Array with no underlying storage (do we want to allow this?), i.e. before init is called, len will run into a segmentation fault.

This is especially annoying if you only want to try it out in an ipython shell and the line `pyarrow.array.Array()` directly crashes as IPython tries to print the repr.
