The assert macro usage should not produce 3 clang -tidy ...

assertis part of the C++ (or C) implementation and so it is useless for clang -tidy to check it and tell you to fix it. Just because the check doesn't make sense for assertdoesn't mean it's useless elsewhere, and it's silly to infer that that's what I meant.

static_assert declaration - cppreference.com

A static assert declaration may appear at namespace and block scope (as a block declaration) and inside a class body (as a member declaration). If bool_constexpr returns true, this declaration has no effect. Otherwise a compile-time error is issued, and the text of message, if any, is included in the diagnostic message. message can be omitted.

Safety: assert in debug mode when on demand values are ...

Essentially, you are delaying the parsing of "x" until the cout line, but then you go and grab the "y" field in between, which skips "x". Then when you do uint64_t(x), you actually get the value of "y" (2) because that's where the iterator is now.. This PR adds an assert that occurs when this happens.

Clang Language Extensions — Clang 12 documentation

Clang also provides a set of builtins which can be used to implement the <stdatomic.h> operations on _Atomic types. Use __has_include(<stdatomic.h>) to determine if C11's <stdatomic.h> header is available. Clang will use the system's <stdatomic.h> header when one is available, and will otherwise use its own. When using its own ...

clang -tidy - bugprone- assert -side-effect — Extra Clang ...

Finds assert () with side effect. The condition of assert () is evaluated only in debug builds so a condition with side effect can cause different behavior in debug / release builds.
