The owner of methods defined after using Module#prepend seems to be incorrect.

 RUBY_DESCRIPTION # => "ruby 2.1.0dev (2013-03-01 trunk 39546) [x86_64-linux]"
 
 class C
   attr_reader :a
   prepend Module.new
   attr_reader :b
 end
 C.instance_method(:a).owner # => C
 C.instance_method(:b).owner # => #<C:0x00000000a52300>
 C.new.method(:a).owner      # => C
 C.new.method(:b).owner      # => #<C:0x00000000a52300>
 
 module M
   attr_reader :a
   prepend Module.new
   attr_reader :b
 end
 M.instance_method(:a).owner # => M
 M.instance_method(:b).owner # =>
 # ~> -:19:in `<main>': undefined method `class' for #<M:0x00000000a515b8> (NoMethodError)
