I must admit that I haven't used quilified names that much since I prefer a
using namespace XXX in my .cpp files.
However, when overloaded versions cannot co-exist (because of ambiguity), I
kind of like the idea of aliasing.
I think with names like

namespace str = boost::algorithm::string;
namespace cont = boost::algorithm::container;

One can always find the name that seems reasonable readable while still
reasonable short.

If it would work, I would like it. But I suspect that enable_if coding would
be
necessary to disambiguate overloaded functions.
