Ah but with slicing the inputs, you must check the length first
so that you don't get an out of bounds error. I would prefer it 
if cmp
did this for me, since it is going to check lengths anyway. 
Example below.

private void ParsePacket(in char[] data)
{
     static string Good = "GOOD";
     static string Bad = "BAD";

     if (data.length >= Good.length) // Prefer not to do this check
     {
         if (std.algorithm.cmp(data[0 .. Good.length], Good) == 0)
     }
     else if
     {
         // Check Bad, and so on
     }
}
