Quuxplusone added a comment.
I should add that if any particular library really wants to //enforce// "thou
shalt not deep-link <https://en.wikipedia.org/wiki/Deep_linking> detail
headers" (instead of just documenting it and/or relying on the
user-programmer's common sense) they can do it pretty cleanly via macros:
// toplevel.h
#pragma once
#define DONT_INCLUDE_DETAIL_HEADERS_DIRECTLY(x, y)
#include <__utility/foo.h>
#include <__various/bar.h>
#undef DONT_INCLUDE_DETAIL_HEADERS_DIRECTLY
// more code here
and then
// __utility/foo.h
#pragma once
DONT_INCLUDE_DETAIL_HEADERS_DIRECTLY(instead, include <utility>)
class Foo {};
void foo();
I don't know how you'd achieve a similar effect with C++20 Modules, but I
certainly hope it's possible somehow.
