Materializes and reindexes the current data into a series of sequential integer keys.

<p>Access {@see all()} on the result to get the resulting array.

<p>This is useful to extract the data as a linear array with no discontinuous keys.

><p>This is faster than {@see reindex()} bit it materializes the data. This should usually be the last
operation to perform before retrieving the results.
