Is your Qt code "outdated" because you're using raw pointers for your UI classes?

Jesper Pedersen asked Peppe (Giuseppe D'Angelo) about the design choices behind Qt Creator's templates, and we covered everything from unique_ptr trade-offs to the mysterious empty destructor.

Questions for compilers connoisseurs:

There is an obvious simplification in this expression :

(2*N0f[i] + N1f[i] + (N0s[i] - N0f[i]))

but keeping it as is makes it simpler to read again later (to understand what is computed here). Good alternative: I make the simplification and I add a line of comment — that might be the best solution, both for future code maintenance and for performance.

However I was wondering if the compiler do this kind of simplification? Or do I have to add -funsafe-math-optimizations or some other options?
