Not just parseargs, but any other methods that the method calls. In your case, it was simply p, but in some other case, I might be passing a parameter all around the system, in which case, who knows what it'll need. (Is that bad design? If so, that's precisely one of the things I want to flesh out as an extra restriction we need to place on ourselves because we're using Ruby.)

def method(*argv)
pa = parseargs(argv){
arg :x, :ducktype => File.new('methods.txt').readlines.each { |line|
line.chomp
}
}
p pa.x.upcase.downcase
end
