+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.
