boost::copy is a range-based version of std::copy. It's not ambiguous because it doesn't have the same arity.
Anyway, it's probably not a good idea to do "using namespace boost", just like you shouldn't do "using namespace std"...
+1 - it will come round and bite you eventually (or some poor unsuspecting maintainer). And Boost's many examples should NOT set a bad example by doing "using namespace boost". IMO "using boost::a_library::a_function;" is actually much better, despite being longer, because it makes clear where the function comes from. Authors NB! Paul --- Paul A.
