I'm not unfamiliar with Boost.ConceptCheck, though I've used it very  
infrequently. So, like all familiar but infrequently used libraries I skip  
to the examples to jog my memory as to their usage. Invariably, if the  
examples or the tutorial are not complete then I end up repeating past  
mistakes. This is the case with Boost.ConceptCheck library. All the  
examples on this page:  
http://www.boost.org/doc/libs/1_56_0/libs/concept_check/using_concept_check.htm  
(which is the quick 5 minute introduction on how to use ConceptCheck)  
assume some previous "using namespace boost;" declaration, yet that is not  
documented on that particular page or any previous page. Can this be fixed  
to save new and infrequent users of the library unneeded head-scratching  
and wasted time? (I can open a trac ticket if that helps.)

Thanks.
