So I'm wondering to do this now. I want to be explicit so a reader knows I explicitly set the initial value of this array in that structure to all zeros. My argument is that D initializes not with the most convenient, but the most wrong value in order to provoke reproducible errors. So in general you should initialize to sane values.
That's not entirely true. For integers, the initialization is always 0, which is expected and convenient.
For characters, it's 0xFF, because what else are you going to initialize it to? space? Given there is no standard default initial value, D chose the mostest garbage value possible (but in a defined behavior).
As for floats, well, arguably, I prefer the NaN behavior, because floats are very strange beasts, and the initialization scheme reminds me that there are many many many pitfals to remember.
