 You can probably have amore precise value, but just to give you an example
 here the nodes needed for a small method

pigeon% cat b.rb
#! /usr/bin/ruby -rii
def method(*args, &block)
   old_method
end
dump Object, :method
pigeon%

pigeon% b.rb
Method Object::method
SCOPE
  BLOCK
    ARGS (*args)
    BLOCK_ARG (&block)
    NEWLINE <./b.rb:3>
    VCALL old_method 
 
pigeon% 

 You just need to look at each node and make the sum of all bytes used :-)


p.s.: there is a big reason for attribute accessor because ruby, in this
case, use *only* one (1) node
