If dependencies are resolved at compile time, why does the 
compiler include extra stuff?

Did you compile with LTO?  If not, the exe may carry extra baggage,
since the linker may not have tried to shed excess baggage.

You are right! Test results on linux:

```d
//import std.stdio : writefln;/*
version = 1;
import core.stdc.stdio : printf;//*/


void main()
{
   string hello = "hello";

   version(1)
   {
     printf("%s world\n", hello.ptr);// 6464 bytes with strip
   }

   else hello.writefln!"%s World!";  // 196KB with strip
}
/*
  * ldc2 -O hello.d -release
  */

```
