Subject: Subclassing in module from top module?

Hello everybody,

I would like to have locally monkeypatched Hash in my module. I would
expect that following example will work, however it doesn't. How to do
it correctly?

irb(main):016:0> module Foo
irb(main):017:1>     class Hash << ::Hash
irb(main):018:2>         def bar
irb(main):019:3>             puts 'bar'
irb(main):020:3>           end
irb(main):021:2>       end
irb(main):022:1>   end
SyntaxError: (irb):17: syntax error, unexpected tLSHFT, expecting '<' or
';' or '\n'
  class Hash << ::Hash
               ^
        from c:/Ruby/bin/irb:12:in `<main>'



Cheers,

Vit
