Scope Guard

Implementation of Scope Guards (scope_exit, scope_success, scope_fail) and unique_resource as proposed in P0052R10.

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).

Standardisation progress

P0052 has been adopted (2019-03) and is in the Library Fundamentals v3 now.
