Headers really shouldn’t be affecting each other. Header order shouldn’t matter. The fact that it does is arguably a bad design flaw in C/C++, although the C mo

That is, clang-format offers a crude but simple API to the programmer to express which headers have order dependency, and which don't. Given that headers can have order dependency, it is sadly part of a C++ programmer's responsibility to know which do, just as it is their responsibility to know which functions have side-effects, etc. If they are using clang-format, it is then their responsibility to communicate this knowledge to it.

      The simplest way to communicate that this anti-feature is unwanted is to add this to your clang-format: SortIncludes: false
