Re^2: Solving compositional problems with Perl 6 roles

That would imply that the possession of one trait implies the removal of another. Now, you're starting to talk Prolog-style levels of compiler knowledge. While this wouldn't necessarily be a bad thing, and would be implemented in the definition of the trait, I can see how this would be quite reasonably construed as some serious action-at-a-distance ...

I'm not sure what you mean by "That..."? `... does Program, Manage, FirstAid;` [download] was meant to imply the equivalent of `... does Program does Manage does FirstAid;` [download] 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 ...) ------ We are the carpenters and bricklayers of the Information Age.
