Bryce claims that the procedural version will be much cleaner. Let's see some actual proof.
I didn't claim that. I only claim that it will not be objectively worse.
The real benefit would probably be that a p/r version would be more consistent from developer to developer because OO is too open-ended. Every professed OO guru does a very different design. OO is all over the fricken map because it the Goto of structuring. Relational rules and the "group by task" of procedural will tend to produce a more consistent and predictable result than OO.
