Scope Guard

Implementation of scope_guard and unique_resource as proposed in P0052R5 (former N3949).

Compatibility

This implementation conforms to P0052, except:

Namespace

The namespace sr is used instead of std.

Filenames

The filenames contain a .h extension. To enable the compatible header as specified in the document the CMake option ENABLE_COMPAT_HEADER can be used. This will generate and install an additional header named scope (without file extension).

std::uncaught_exceptions()

The function std::uncaught_exceptions() is not available in C++14 and is therefore replaced with std::uncaught_exception(). This has some limitations, but is the only solution until C++17 is used.

Implementation decisions

Factory functions

The Factory functions for both types are kept for the C++14 implementations as deduction guides aren’t available.
