Research direction
Start by reading this issue and its references to gsl_lite, the C++ Core Guidelines, and P1132 out_ptr. The payload does not identify files, tests, an implementation entry point, or acceptance criteria; done would require an agreed rationale and scope for retaining or removing unique_resource.
Written by the indexing model from the issue text.
Description
After looking at some other libraries like gsl_lite and even the core guidelines, they don't have unique_resource. What is the value of this type of unique_ptr with a deleter? For the file handle case so commonly cited unique_ptr may be used in combination with the c++23 std::out_ptr - this repo for an example from the paper [P1132 out_ptr - a scalable output pointer abstraction] (https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p1132r8.html#design-casting-similar).
So given the existence of P1132 is there any actual rational for this type?
