I actually prefer Steven's interpretation. If we are going to iterate 
directly on a path object, we should be yeilding the pieces of the path 
object. After all, a path can contain a file name (most of mine do) and 
what sense does it make to iterate over the children of 
/usr/home/ethanf/some_table.dbf?
