Will it be possible to manipulate this stack? Like

class A
   def foo
   end
  def foo:pre
     p 1
  end
  foo:pre
     p 2
  end
 
  foo:pre
     p 3
  end
   
  remove_pre_method :foo  
  # maybe add the position like
  remove_pre_method :foo,1
end 

or do I have to just live with my hook method stack
- i.e. only addition to this stack will be possible?

What will happen to this stack if I redefine the
main method? Will this kill the current stack of
hook methods?
