    I implemented all the Common Lisp features (of which the package
    system was one) in the Lisp Machine operating system, which included
    lots of programs to do lots of things.  (An Emacs-like editor was one
    of them.)
    
    In practice, the goal of using names without prefixes via importing
    namespace did not work out.
    
    I make the conjecture that name space importing is convenient when you
    have lots of small modules, each with its own name space and not many
    names, and each referring to just a few other modules.  That's not how
    the Lisp Machine system was written, and it's also mostly not how
    Emacs was written.
