Fair enough -- I mainly wanted to point out an important distinction blurred by "why vs. what". It's up to the context whether you'd care more about this kind of why or what. However, it's this what -- what the code is meant to do -- that's both the most basic info for maintenance and in poorer supply, as I've seen it. It's often easier to get an off-the-cuff answer to "why do that?" (or to not need it) than "exactly what was this code meant to do? Does the rest of the system depend on the fact that it freems the bleetches, or can I change that?" -- in that case you're more likely to get back "Hm, I'd better read all this related code to swap it into my head". Your experience might be different, and that'd be kind of interesting.
