How do they say... all generalizations are false? :o)

I disagree. There are coding guidelines that are generally accepted within
reason and when the forces are properly explained. For example, virtual
functions are preferable to switching on type, for objective reasons
(modularity, extensibility, flexibility). Now there are cases when that
guideline won't apply, so as long as those cases are identified and spelled
out, I think that is a fair coding guideline on which most reasonable people
would agree.

In fact, here's a little guideline that everybody would agree with. :o)
