  Log:
    * doc/syntax/assignment.rdoc (Local Variables and Methods):  Fixed
      example showing caching of a method's results into a local variable.
      Added not about using an explicit receiver to call a method that
      matches a local variable.  Suggested by markov_twain on twitter.

-  big_calculation = big_calculation
+  big_calculation = big_calculation()
 
 Now any reference to +big_calculation+ is considered a local variable and will
 be cached.  To call the method, use <code>self.big_calculation</code>.
 
+You can force a method call by using empty argument parentheses as shown above
+or by using an explicit receiver like <code>self.</code>.  Using an explicit
+receiver may raise a NameError if the method's visibility is not public.
+
 Another commonly confusing case is when using a modifier +if+:
 
   p a if a = 0.zero?
