I still think that it should be the default behavior unless no-initialization
was specifically requested, like the case for uninitialized arrays.

The spec says "Members not specified in the initializer list are default
initialized" for *static* objects. So this works:
static S s = { 42 };
dout.writefln(s.d); // prints nan
This check fails though:
assert(s.d == double.nan);
and it is probably not meant to work anyway; because I see that the spec at
http://www.digitalmars.com/d/2.0/float.html
has this to say (probably recently modified):
x == x â true not valid if x is a NaN

Good: That does set s.d... :)
