We use separates to keep (re)generated package specs and bodies well
away from the handwritten parts --having had some bad experiences with
Rose/Ada (special --begin-handwritten, --end-handwritten comments and
lots of opportunities for confusion).

Also sometimes useful for AUnit testing -- put the test case into a
package whose body is separate.
