With -std=c++17 (which is the default now), the code is optimized as expected.
With -std=c++14, the dynamic initializer comes into play; there are a few other
bugs dealing with that already too.

If that's the case then it should get automatically resolved once C++17 is
implemented - C++17 introduces constexpr lambdas.
But it would be great to have this optimization also in C++14 mode.
