Alternatively, make your own methods on the objects themselves, giving them
whatever consistent naming scheme you feel like:

class Object
  def meta_class
    Object.instance_method(:class).bind(self).call
  end

  def meta_send(*args)
    Object.instance_method(:send).bind(self).call(*args)
  end

  #def method_missing(meth, *args)
  #  return Object.instance_method($1).bind(self).call(*args) if
  #         /^meta_(.*)$/ =~ meth.to_s
  #  raise NoMethodError, "undefined method '#{meth}' for #{inspect}"
  #end
end

class Foo
  def send(*args)
    "whoo!"
  end
  def class
    "stupid!"
  end
end

f = Foo.new

puts f.class                     # stupid!
puts f.meta_class                # Foo

puts f.send(:object_id)          # whoo!
puts f.meta_send(:object_id)     # -605608944
