Dear Boost Community,

I've been following this list for a time with the desire of contributing to
Boost. It seems to me a good idea to start with small and easy to review
proposals, before attempting anything big.

So my first shot is shared_handle class, an alternative to
enable_shared_from_this that doesn't suffer from multiple inheritance
issues. It also provides the capability of instantiating a shared_ptr to a
member object.

Unfortunately, the implementation produces at least one regression: clang
3.1 crashes when it compiles cpp11_pointer_cast_test.cpp with -std=c++11.
There may be others since I couldn't test in all compilers used in the
regression tests.

Nevertheless, is there any interest?

Kind regards,
Roberto Hinz
