When you submit a program unit for compilation, the compiler has to
assume that if all you wanted was to change a comment and get a compiler
listing, you would have had the sense to do the compilation in a temporary
program library rather than recompile a fundamental specification and
thereby invalidate everything (probably the entire software system) that
was compiled against that particular specification.
If you had changed something substantive, then the recompilation would
be necessary in order to propagate the effects of the change throughout
the system. It would have to be a fundamental semantic or syntactic
change, since if it were merely an implementation detail the effects
would have been confined to the package body.
