Description updated ---------------------------------------- Bug #11283: Block assigned implicitly https://bugs.ruby-lang.org/issues/11283#change-53021 * Author: Andrew Kozin * Status: Open * Priority: Normal * Assignee: * ruby -v: 1.9.3, 2.0, 2.1, 2.2, ruby-head * Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN ---------------------------------------- That is how it works: module Test def self.build(&block) klass = Class.new(Object) klass.__send__(:define_method, :foo) klass.__send__(:define_method, :bar) klass end end Tested = Test.build { :foo } # warning: tried to create Proc object without a block # => Tested Tested.new.foo # => :foo Tested.new.bar # => :foo The block is assigned to all calls to `:define_method` via `Object#__send__` implicitly, while it wasn't asked to. The behaviour is tested under MRI 1.9.3, 2.0, 2.1, 2.2, ruby-head. It doesn't occur under rbx-2 and jruby (1.7, 9.0.0.0).
