Subject: Re: Kernel.xxx interferes with method_missing

Possible solution, a hack with redefining all global methods.

  class ExtraBlankSlate < BlankSlate
    CUSTOM_UNDEFINE = [:p, :select, :puts]

    undefine = Kernel.instance_methods + Object.instance_methods + 
CUSTOM_UNDEFINE
    BlankSlate.instance_methods.each{|m| undefine.delete m}

    undefine.each do |m|
      script = %{\
  def #{m} *p, &b
    method_missing :#{m}, *p, &b
  end}
      class_eval script, __FILE__, __LINE__
    end
  end
