Thanks for these articles. Any chance they will appear in a single
location, so we don't need three separate URLs for them?
Also, one article passes on this recommendation:
use super consistently, and document that you use it, as it is part
of the external interface for your class, like it or not.
So, if use classes coming from a library in a multiple inheritance
situation, you must know if the classes were intended to be
cooperative (using super) or not. Library author should always
document their usage of super.
I can see lots of ways this fact could be documented, none of them
terribly concise. It's a simple “yes/no” fact about a class, after all;
what's the best way of succinctly conveying this information in a world
where the problem is barely known, let alone the solution?
