Methods are generated in a loop with define_method. For `Roles.new(:editor)`, what do `admin?`, `editor?`, and `viewer?` return?

class Roles %i[admin editor viewer].each do |role| define_method("#{role}?") { @role == role } end def initialize(r) = @role = r end u = Roles.new(:editor) [u.admin?, u.editor?, u.viewer?]
