Casting in this case means reinterpreting the bytes of the 
`string` as if it were a `dstring`. For this to work, the string 
would have to start at an address and have and address divisible 
by 4, which it evidently doesn't.

Anyway, what you want is:

     import std.conv : to;
     string a = "Hello, world!";
     dstring b = a.to!dstring;
