Well, for the very good reason that it works.  Right now there is a  
working namespace if you compile objects as individual files.  There is  
no namespace with objects compiled into libs, and even worse, all  
symbols are loaded when a lib is loaded whether or not they are used.

Plus packaging objects as individual files means that there can easily  
be a common library format for all objects, no matter what language  
they are written in, compiled or not.

Also, there is a strong precedent for this:  Java's jars.  They are  
directories with individual .class files compressed into a .zip file  
named .jar.
