Not too clearly written, sadly. For instance
Now that all classes must be able to call sqr', let's try to call sqr’ to `self’:
print self.sqr(5)
^D
ERR: private method `sqr’ called for (Object)
Calling the function using `self’ after the definition of the function
gives the error as shown above. The error message is not intuitive, so
what does it mean?
What is happening is that a method that is defined at the top levelcan
can be called using function style as opposed to method style. See
what error message you get when undefined methods are called.
would leave me no wiser than befre.
