Provides a similar "API" to Microsoft's C++20 modular standard library (std.core, std.threading, etc.). This can be either imported as a submodule or you can download the latest release with just the headers.
For example, instead of
import std.core;
You use
#include <std/core.hpp>
There is also a "c.hpp" for the libraries inherited from C in the C++ standard library, and also a "library.hpp" for including the entire C++ standard library all at once.
Newer headers not yet implemented in MSVC will be guarded by feature-testing macros.
