Bug #4401: override :method method breaks Psych
http://redmine.ruby-lang.org/issues/4401

Author: Lin Jen-Shin
Status: Closed
Priority: Normal
Assignee: Aaron Patterson
Category: ext
Target version: 1.9.x
ruby -v: ruby 1.9.2p136 (2010-12-25 revision 30365) [x86_64-darwin10.5.0]

 I am not sure if this could be considered a bug, but it used to work.
 To reproduce it:
 
 ruby -r psych -v -e 'Psych.dump(Struct.new(:method).new)'
 ruby 1.9.2p136 (2010-12-25 revision 30365) [x86_64-darwin10.5.0]
 /usr/local/Cellar/ruby/1.9.2-p136/lib/ruby/1.9.1/psych/visitors/yaml_tree.rb:48:in `method': wrong number of arguments(1 for 0) (ArgumentError)
         from /usr/local/Cellar/ruby/1.9.2-p136/lib/ruby/1.9.1/psych/visitors/yaml_tree.rb:48:in `accept'
         from /usr/local/Cellar/ruby/1.9.2-p136/lib/ruby/1.9.1/psych/visitors/yaml_tree.rb:36:in `<<'
         from /usr/local/Cellar/ruby/1.9.2-p136/lib/ruby/1.9.1/psych.rb:165:in `dump'
         from -e:1:in `<main>'
 
 I don't have a good idea how to fix it,
 but here's some demonstration:
 
 https://github.com/godfat/ruby/commit/f4e0e8f781b05c767ad2472a43a4ed0727a75708
 https://github.com/godfat/ruby/commit/c7a6cf975d88828c2ed27d253f41c480f9b66ad6
 
 Patches attached as well, the same as above two commits.
 I think they are against r30885.
 
 Many thanks!
 
 p.s. this issue was found in delayed_job's:
 class PerformableMethod < Struct.new(:object, :method, :args)
