An example of what? a Child package that extends its parent is another feature 
for programming by extension.

For examples of how programming by extension emphasizes ease of writing over 
ease of reading and the like, see some articles I had in /Ada Letters/:

Carter, J. R., “Ada’s Design Goals and Object-Oriented Programming,” /Ada 
Letters/, 1994 Nov/Dec

Carter, J. R., “Breaking the Ada Privacy Act,” Ada Letters, 1996 May/Jun
