UniqueResource, a C++ template class as a universal resource manager

[WhoCares]

There is no silver bullet

Such unique/scope resource managers never consider dependencies.

There is also std::experimental::scope_exit() for RAII.

M$FT wrapped the Win API using MFC for that reason as they could construct the hierarchy and encapsulate handles. Not to say this technique isn't usable in some common and simple everyday scenarios.
