There were examples in the linked message board post [1]. Note how there is now a paragraph describing why the code is written with 4 casts instead of comparing pointers naively. Multiply this by hundreds of instances of similar code in a large code base.

Why not just write a function is_ptr_less that does all the casts.

P.S: In C++ std::less is guaranteed to do the right thing(tm).
