I tried this without luck:
struct __GUID{
static __GUID opCall( uint Data1_, ushort Data2_, ushort Data3_, 
ubyte[8] Data4_ ){
     __GUID s;
     s.Data1 = Data1_;
     s.Data2 = Data2_;
     s.Data3 = Data3_;
     s.Data4[0..8] = Data4_[0..8];
     return s;
}
align(1):
uint Data1;
ushort Data2;
ushort Data3;
ubyte[8] Data4;
}
alias __GUID GUID;

GUID IIDFromString(char[] d) {
     return GUID(1,2,3,[0,1,2,3,4,5,6,7]);
}
