#3704: Incorrect boost::decay documentation
--------------------------------------------+-------------------------------
 Reporter:  Kenneth Ho <ken@…>              |       Owner:  matias       
     Type:  Bugs                            |      Status:  new          
Milestone:  Boost 1.42.0                    |   Component:  Documentation
  Version:  Boost 1.41.0                    |    Severity:  Problem      
 Keywords:  decay type_traits               |  
--------------------------------------------+-------------------------------
 The first row of table '''1.10 Examples''' in
 [http://www.boost.org/doc/libs/1_41_0/libs/type_traits/doc/html/boost_typetraits/reference/decay.html

 boost::decay] doc states the result of '''{{{decay<int[2][3]>::type}}}'''
 is '''{{{int[2]*}}}''' (where lowest array bound removed), which is
 incorrect and is actually '''{{{int[2]*}}}''' (where topmost array bound
 removed). Unlike the former, the later behavior is consistent with
 [http://www.boost.org/doc/libs/1_41_0/libs/type_traits/doc/html/boost_typetraits/reference/remove_extent.html

 boost::remove_extent].

 Also, the description of '''type''', quote: '''"... the result is
 remove_extent<U>* ..."''', would've been more accurate if it was '''"...
 the result is remove_extent<U>::type* ..."'''
