#7231: Boost ICL "party" example fails compilation using Clang 3.1
-------------------------------------------------------+--------------------
 Reporter:  Jess Morecroft <jess.morecroft@…>          |       Owner:  jofaber
     Type:  Bugs                                       |      Status:  new    
Milestone:  To Be Determined                           |   Component:  ICL    
  Version:  Boost 1.49.0                               |    Severity:  Problem
 Keywords:  clang icl                                  |  
-------------------------------------------------------+--------------------
 Test program copied exactly from "party" example in boost icl
 documentation (attached). Compile fails on Mac OS X 10.8 (ML) using latest
 Clang - version below. (compiles OK using gcc)

 Looks like Clang is not picking up the operator+= template in the concept
 header? Probably a Clang bug and if so sorry for the ticket! ...
