   > This looks good to me.

   > The proper solution would be to extend `Diff` with support for chunked 
arrays. Currently a diff between `[1, 2], [4, 5, 6]` and `[1, 2], [3, 4, 5, 6]` 
will simply report the different lengths rather than showing the diff, which 
would be fairly meanginful in this case. Additionally, when requiring chunk 
layouts to be equal the diffs can be very messy since it proceeds chunkwise. 
This need not be addressed in this PR, but please add a follow up JIRA
