This huge writeup would probably belong more in Documentation/
Hi Dave,
Surely you did not mean to characterize his documentation as blather? It seems
to be of very good quality, we need to encourage that level of diligence. As
far as moving it to Documentation goes, my immediate reaction is I sure do like
it when the coder cares enough about my understanding of what he's doing to
put such effort into trying to make sure I understand what he's doing and why
he's doing it. Having it right in the code removes a level of indirection when
reading that might make the difference between me reading and not reading the
documentation, which in turn might make the difference between understanding and
not understanding the code. Agreed it's a bit much at least all in one piece.
Maybe precis the in-line documenation and move the greater literary effort to
Documentation, with the requisite "see Documentation/" line?
Regards,
Daniel
