Scope Guard

Implementation of Scope Guards (scope_exit, scope_success, scope_fail) and unique_resource as proposed in P0052R5 (former N3949).

There’s a C++14 implementation on the cpp14 Branch.

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).

Implementation decisions

Factory functions

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