Most of that seems reasonable, but the "do not use function pointers" boggles my mind. I'm pretty sure the alternative is a bunch of conditionals wherever you would otherwise use a function pointer. I've definitely seen some really ugly code written with this axiom which would certainly be a lot cleaner if rewritten to use function pointers. I'm curious if anyone can make a compelling argument against function pointers?

It's in the original:

> […] Similarly, function pointers should be used only if there is a very strong justification for doing so because they can seriously restrict the types of automated checks that code checkers can perform. For example, if function pointers are used, it can become impossible for a tool to prove the absence of recursion, requiring alternate guarantees to make up for this loss in checking power.

In other words, static analysis beats code cleanliness, in this perspective.
