Subject: [ruby-core:22419] Re: [Patch 191p0 ] for ostruct freeze behavior

I was about to file an error report.
When I found this
http://redmine.ruby-lang.org/repositories/diff/ruby-19?rev=22332 ?

I wonder if I still shall add this error report, as the fix seems
incomplete ( So would have my patch BTW. That is why I have backed up
Jo�l's idea to forward freeze to @table or to a pseudo object in case
one wants to keep table unfrozen for some unknown reasons )


require 'ostruct'

class OpenStruct
  def frozen?; false end
end

o = OpenStruct::new( :a => 42 )
o.freeze
o.a = 1
p o.a

IOW it is fragile to rely on #frozen? JRuby's implementation is
suffering from the same problem BTW.
