#1947: traversal access decoupling

Milestone:  Boost 1.36.0      |   Component:  iterator
  Version:  Boost 1.35.0      |    Severity:  Problem 
 Keywords:                    |  
------------------------------+---------------------------------------------
 In an attempt to use iterator_facade to
 implement a "Readable" and "Writeable"
 == "Swapable" "Random Access" iterator
 I found that the expression:
 it[n] returns an object of type
 operator_brackets_proxy that is convert-
 ible to "reference" but not to "value_type".

 Consequently I can use

 value_type a;
 it[n] = a;

 but not
 a = it[n];

 I am not sure of how to correctly solve
 this issue. Here is a pointer to a
 discussion on the list:
