Daily bit(e) of C++ | Partial ordering of constrained function overloads
Daily bit(e) of C++ #311, C++20 partial ordering of constrained function overloads.
Since C++20, functions can be constrained, establishing a partial ordering of function overloads.
If multiple candidates satisfy a function invocation, the candidate with the most specific constraint will be selected.
For practical purposes, this allows for specialized implementations that take advantage of additional features provided by the arguments.
