Thanks a lot! I will change all my initialisations to static 
constructors now.
The only additional problem I have, is that ℚInf has a disabled 
default constructor.
Is there a way to allow shared static constructors, but not the 
default constructor?
struct ℚInf {
     ℚ qval;
     immutable static ℚInf zero;
    @disable this();
     shared static this() {
          zero.qval = ℚ(0);
     }
     this(long num, long den) {
          qval = ℚ(num,den); //this initialisation requires
 dynamically linked code
      }
}

Best,
Kevin

I should perhaps add, that I get the following DMD error message:
source/intervalarithmeticrationals.d(15): Error: variable 
intervalarithmeticrationals.ℚInf.posinf default construction is 
disabled for type immutable(ℚInf)
