class A
def initialize(string)
    @string = string
end
def execute(regexp, truth=true)
    if (@string =~ regexp) == truth then
        # ...
    else
        # ...
    end
end
end


class B
def execute(a, regexp)
    a.execute(regexp, false) # ERROR... How should I do?
end
end

B.new.execute(A.new("foo"), /bar/)
