Sorry David, your a little late to make claims on that one. If you read my AOP
RCR (which by the way I think I've plugged like six times now) you would
notice that I offer:

wrap w
super
print "W"
end

as a backup alternative to my primary proposal, which I belive to be a far
superior:

class C
def x
puts "how are you?"
end

def x
puts "hello"
super
puts "goodbye"
end
end

Before anyone looks at this and crys "foul!", read the dang RCR.
