Not at all. I've been using Ada since 1984, and am reckoned to have a passable understanding of it. I am reasonably familiar with the programming-by-extension features (see my use of a type extension to avoid access types in a recent discussion of S expressions), but I have made several errors when dealing with code that uses these features in their more normal, obfuscatory manner. Normally I would think it's just a failing on my part, but the many problems others have had help me think that maybe it's not. HOOD is a design method, and has nothing to do with programming by extension, which is an implementation technique that has nothing to do with object orientedness. I've have written plenty of object-oriented S/W that does not use programming by extension, and (unfortunately) seen far too much S/W that uses programming by extension that is not object oriented. -- Jeff Carter "Blessed are they who convert their neighbors' oxen, for they shall inhibit their girth."
