Hi Robert,

It’s generally not an item on the roadmap to make constexpr everything that can be. But when we touch code with expressions that could be constexpr, then we might make that change as a drive-by, if the code would otherwise benefit from it.

If there’s any part of Qt where you’d see significant value from making things constexpr, then you’re welcome to push things for review.

Cheers,
Volker
