Nice article, very pleasured to read. One thing that strained my mind - this 
exaple:

>import std.stdio;
>
>char[] fillAs(char[] buf, size_t num)
>{
>   if(buf.length < num)
>      buf.length = num; // increase buffer length to be able to hold the 
> A's
>   buf[0..num] = 'A';   // assign A to all the elements
>   return buf[0..num];  // return the result
>}
>
>void main()
>{
>   char[] str = new char[10];   str[] = 'B';
>   fillAs(str, 20);     // buffer must be reallocated
>   writeln(str);        // "BBBBBBBBBB"
(1)
>   fillAs(str, 12);     // buffer can be extended in place!
>   writeln(str);        // "AAAAAAAAAA";
>}

Please add in (1) assert(str.capacity == 15);
