I'm not sure what you mean by "That..."?

... does Program, Manage, FirstAid;

was meant to imply the equivalent of

... does Program does Manage does FirstAid;

with $individual stops FirstAid; removing the latter Role when appropriate.

Unless your referring to the last bit about the compiler mapping $individual does Thieving; to $individual isn't Employee;, in which case, my attempt at humour failed completely.

    Actually, I think that your attempt at humor was actually a good idea, in disguise. I can see where one would like roles to be exclusionary - if $foo does X, that means you cannot have $foo does Y, so there should be a way of specifying that in the definitions of X and Y. But, as I said earlier, this is starting to sound like Prolog. (Not necessarily a bad thing, mind you ...)

    I shouldn't have to say this, but any code, unless otherwise stated, is untested
