how to initialize nested struct elegantly?

[elvisxzhou]

import std.stdio;

struct AA
{
     int i;
     char c;
     double d;
     string s;
     float f;
}

struct BB
{
     float f;
     AA[2] a;
}

void print(BB* bb)
{
     writefln("bb.a[0].i=%d bb.f=%f", bb.a[0].i, bb.f);
}

void main()
{
     //dlang
     AA aa = {
         i:1010,
         f:0.1f
     };

     BB bb = {
         f : 0.2f,
         a : [
                 AA(1010, 0,0,null,0.1f),
                 AA(1020,0,0,null,0.2f)
             ]
     };

     print(&bb);

     /************************************************/
     /*

     //C99
     print( &(BB){
         .f = 0.2f,
         .a = {
             [0] = { .i = 1010, .f = 0.1f }
             [1] = { .i = 1020, .f = 0.2f }
         }
     });

     */
}


dlang version has two unnecessary symbols aa and bb, which is 
ugly compare to c99 one.
