    For objects, it would be nice to know:
    
    * Do they have an entry part, array part, and/or a hash part?
    
    * What are the allocated vs. used sizes of each part?
    
    * What is the array density (estimate or accurate computation)?
    
    * What is the estimated memory footprint of the object?
