Would be nice if Dask Collections implemented a to_chunks method (or other name) that amounted to creating a list containing each chunk wrapped up as a Dask Collection. As an example a Dask Array would be turned into a list of Dask Arrays (one for each chunk). A nice option to include with some of these methods would be to add in the selection (or similar) required to get that chunk from the whole. Returning to the Dask Array case, this would be the slicing.
