void initialization of class fields

[Andrej Mitrovic]

This is a modified example from TDPL, page 185-186, although I've increased the size of the array here:

class Transmogrifier
{
    double[512] alpha = void;
    size_t usedAlpha;
    
    this()
    {
    }
}

void main()
{
    auto t = new Transmogrifier;
    writeln(t.alpha); 
}

This will write 512 zeros in my case. If I understood correctly, then alpha is an array containing 512 uninitialized values. Which is confusing me as to why I'm getting back zeros.

If this was C (minus the classes), I'd get back random values at random locations in memory until I stepped into the wrong place, which would hopefully terminate my app.

I guess I need a primer in how D manages memory, is what I'm really saying. :)
