Hmm...what does 'it' refer to? Does 'it' refers to alias_method?

As far as I can tell, you can't use alias_method with symbols like:

:self.meth_name

for arguments.  However, this seems to work:

class A
  def self.greet
    puts "hello"
  end

  class<<self
    alias_method :old_greet, :greet
  end

end

A.old_greet  #hello
