this works for D too:

import std.stdio;

struct S
{
     int a;
     int b;
}
void main()
{
     S[] s = [{ 1, 2 }];
     writeln(s[0]);
}

OK this does not work but I do not think it is releated to Uniform 
initialization, but it is more something like cast to parametr type or 
something like that

Because there is no need. In c++ it is disaster because there is milion 
way how to initialize something, it is really hard to understand and 
inconsistent
