I wouldn't have removed the Object hierarchy if it wasn't because the  
gains were quite impressive. And this time it wasn't so much a  
performance improvement but a memory usage improvement... many people  
feel uncomfortable with a php application requiring 12 or 16mb to run  
and going from that situation to only requiring 4 or 5mb is good, I  
think, specially for big and busy sites: if they are getting 50 visit  
per second, now plog only needs 50x5 (250) instead of 50x16 (800!) mb  
of memory!!
