Now with code! Will it run the tests?

 LLVM libc clang-tidy checks
 ===========================
 These are the clang-tidy checks designed to help enforce implementation
 standards.
 The configuration file is ``src/.clang-tidy``.
 
 restrict-system-libc-header
 ---------------------------
 One of libc-project’s design goals is to use kernel headers and compiler
 provided headers to prevent code duplication on a per platform basis. This
 presents a problem when writing implementations since system libc headers are
 easy to include accidentally and we can't just use the ``-nostdinc`` flag.
 Improperly included system headers can introduce runtime errors because the C
 standard outlines function prototypes and behaviors but doesn’t define
 underlying implementation details such as the layout of a struct.

 .. code-block:: c++
 
    #include <stdio.h>            // Not allowed because it is part of system libc.
    #include <stddef.h>           // Allowed because it is provided by the compiler.
    #include "internal/stdio.h"   // Allowed because it is NOT part of system libc.
 
 

 LLVM-libc is distinct because it is designed to maintain interoperability with
 other libc libraries, including the one that lives on the system. This feature
 creates some uncertainty about which library a call resolves to especially when
 a public header with non-namespaced functions like ``string.h`` is included.
 
 This check ensures any function call resolves to a function within the
 __llvm_libc namespace.
