  18. In the grammar of the ISO C++ draft, most production rules for lists are
  19. written using left recursion. An exception is the rule for a
  20. mem-initializer-list, for which right recursion is used:
  21.  
  22.           mem-initializer-list: 
  23.                   mem-initializer
  24.                   mem-initializer , mem-initializer-list
  25.  
  26. Why is right recursion used in this case?
