Joris Van den Bossche commented on ARROW-7375:
----------------------------------------------
It could maybe also be a {{pa.nulls(size, type)}} function (in the same vein as
np.empty, np.ones, np.zeros). Although that's of course only a subtle
difference in spelling as the {{pa.null()}} for creating the type ..
