(Someone here on comp.lang.ada made a really convincing illustration of how/where the language uses sets; I wish I could find the discussion.) I thought the secret of Ada was visibility. As it says in /Ada Distilled/, "Once you understand visibility, nearly everything else about Ada will be clear to you." Visibility is similar to the secret of S/W engineering: encapsulation and information hiding. > The blog-post here http://blog.kickin-the-darkness.com/2007/08/fundamental-theory-of-ada.html is one of the best things I've seen simply explaining the Ada mindset.
