I find the separation of spec and body very useful, especially for programming 
in groups by setting detailed design decisions in code-crete as pkg specs. I 
find many of the features of Ada packages useful in representing the 
implementation of a good design. I primarily use body stubs to reduce the size 
of large pkgs.
