iterator

I have a class with a custom each-method:

class CurseArray < Array
    def each_safe
        each.do |element|
            unless element =~ "fuck"
                yield element
            end
        end
    end 
end

And want to call block methods on those "selected" elements. For example:

curse_array.each_safe.magic.collect {|element| "#{element} is a nice sentence."}

I know there is a way to do this, but I've forgotten. Please help! :-)
