address@hidden object allows one to perform common array operations on it
+without loading the object in memory.  In order to reduce memory usage and
+optimize performance, operations on the object are either delayed or executed
+using a block processing mechanism.  Note that this also works on in-memory
+array-like objects like @code{DataFrame} objects (typically with Rle columns),
address@hidden objects, and ordinary arrays and data frames.")
