Could you go and use an overloaded C++11 non-member std::begin( shared_array<> .. ) instead of the member .begin()?

If so then you could try to write a simple generic non-member begin() for the shared_array<> (and ask if it can be added  to boost)?

This is a good example of why the C++11 non-member begin() syntax gives more flexibility.
