Then a cross-referencing tool can connect the dots and produce a useful description of the structure. Annotations could help even further by providing a bit of "why"-knowledge. My feeling is that the same reason that makes naming functions difficult might make writing useful annotations just as difficult. </div><div class="gmail_extra"><br></div><div class="gmail_extra">The dynamic complexity is harder to tame, though. It's about run-time interactions that are best described by message diagrams, protocol descriptions and the like. (Often, the interactions are inter-modular too, but maybe this is not the meso-level you want to document?) I can't see what kind of annotations in the code would help here, except in toy-level examples. For me, this is the part that is usually most difficult to understand when reading code. </div><div class="gmail_extra"><br></div><div class="gmail_extra">best regards,</div><div class="gmail_extra">Vlad</div><div class="gmail_extra"><br></div></div>
