 This will be worst because you need to know for each version what
 possibilities you have.

 To give you an example, one of my extension define an object which is like
 a String object (it try to implement the same methods) : I don't need to
 know when was introduced methods like  #lstrip, #match, ... if I want that
 my object  respond to these methods. In extconf.rb, I just test if a
 String Object respond to one of these methods, and if yes the method is
 defined (via #ifdef)

 And if one of these methods will be removed in the future, my extension
 will still work and respond like a String object
