I understand what I have two visible versions of shared_ptr. And in my
code I exclude all "boost/shared_ptr.hpp" inclusions. But what I have
to do with boost headers such as
"date_time/gregorian/greg_month.hpp" which also include shared_ptrs?
I understand, what 'using' is quite dangerous directive, but I use it
only in implementation files and never in headers. It makes source
code more shortly and readable. Just compare:

std::tr1::bind(&std::tr1::shared_ptr<SomeType>::get,
std::tr1::placeholders::_1, /* ... */);

with

bind(&shared_ptr<SomeType>::get, _1);

:) In the first case code semantic hidden under fully-qualified names.
