datetime64 is different because it has NaT support from the start.  NaN
support for floats seems to be an afterthought if not an accident of
implementation.

And it looks like some errors do pass silently:

>>> a[0] = "1"
# not a TypeError

But I withdraw my suggestion.  The closer datetime64 behavior is to numeric
types the better.
