Because it is consistent with unique_ptr now. You have unique_ptr<T> which
has operator-> and unique_ptr<T> which has operator. Now (as of Boost
1.53.0) you have shared_ptr<T> which has operator-> and shared_ptr<T>
which has operator.
Furthermore, I also contributed boost::make_shared and
boost::allocate_shared for T and T[N]. See:
These do not exist for Boost shared_array, thus prefer Boost shared_ptr
with T or T[N] for arrays if you want an efficient way to create a shared
array: i.e. single allocation with shared_ptr<T> p =
make_shared<T>(size), instead of two allocations with shared_array<T>
