Title: Added element reference operator to methods.rdoc

It seems strange to me that the element reference operator is missing from the methods documentation. While it doesn't use infix notation like the others listed, it is still a special operator method available for people to implement.

[]= is missing as well, but assignment methods are described in the paragraphs above, as well as in assignment.rdoc
