In the 1.9 series, Ruby started always reporting arity -1 for #new. If you want the actual arity of the initialize method, you have to be explicit: {{{ irb(main):001:0> class Test irb(main):002:1> def initialize(arg) irb(main):003:1> end irb(main):004:0> end => nil irb(main):005:0> Test.method(:new).arity => -1 irb(main):006:0> Test.instance_method(:initialize).arity => 1 }}} -- Ticket URL: <http://www.macruby.org/trac/ticket/1454#comment:2> MacRuby <http://macruby.org/>
