Good point.  What about the static version.  ie

//This would be compiled on the fly. It could be put into its own object 
file so it doesn't need to be re-built everytime.
mixin char[] stateMachine(char[] input)
{
  ...
}

void main()
{
     stateMachine("ect...");
}

or

plugin char[] stateMachine(char[] input)
{
  ...
}

void main()
{
      mixin(stateMachine("ect..."));
}

or

char[] stateMachine(char[] input)
{
  ...
}

void main()
{
      mixin(plugin stateMachine("ect..."));
}


Something like that.


I guess malware may still be possible, but you can do that with unit 
tests now.  Essentially these are not much more then unit tests.
