Hi,

There is no such thing as a method inside a method. When you wirte 'def hi', 
you actually define the method 'hi' at the same level than the method 'go2'. 
So, the later cannot acces the data of the former. However, as they are 
defined at the same level, they can share data from the instance variables of 
the class they are defined in.

In any case, there is no point to do this.
