> Example from Python, showing that you can currently create a ChunkedArray with incompatible types:
> {code:python}
> In [8]: a1 = pa.array([1, 2])
> In [9]: a2 = pa.array(['a', 'b'])
> In [10]: pa.chunked_array([a1, a2])
> Out[10]:
> <pyarrow.lib.ChunkedArray object at 0x7fca50704d20>
> [
>   [
>     1,
>     2
>   ],
>   [
>     "a",
>     "b"
>   ]
> ]
> {code}
> So a {{ChunkedArray::Validate}} can be implemented (and which should probably be called by default upon creation?)
