exclude vs override

[kjx]

It seems we have two way of saying (almost) the same thing.

Given:

class sup {
    method foo { print "superfoo" } 
}

then

class sub {
     inherit sup 
     method foo is override { print "subfoo" }
}

and

class sub {
     inherit sup exclude foo 
     method foo { print "subfoo" }
}

do almost the same thing. Do we need both? Differences are

• is override is optional - things still work without it.
• if you exclude something, it goes confidential required, so I think you have to implement it.

Another fun twist: can you override (with is overrides) a method that's been excluded?
it seems like you should be able to, although that doesn't quite make sense.
