In fact, there's a general problem with all coding guidelines. One person was
burned (or believes it's easy to get burned) by a something, so he finds that
something dangerous. Other person was not burned, so he thinks otherwise.
And if no real evidence exists, arguments can become too abstract.

It would be great to have some site, where folks could list designs or
low-level idioms which lead to bugs. That would gather needed evidence.
I used to have such list for myself, so, for example, I'll never write

   for(size_t i = ..., i >= 0; --i)

any more ;-) Of course, creating such global list is very hard.

True. I don't think I was irritated at all -- just run out of arguments. This
was sure a good discussion!
