This is a familiar theme, eh?

Similar to what Steve's pain with the parser, but this is in Harness.pm.

Again, I suspect that these would be more useful as instance data, then 
it doesn't even need a subclass.

On a related note:  making mutators in Parser.pm means we probably need 
something in Harness.pm which is able to mutate them from that level.  
Is there a subref hook available for that?
