eh, yes-ish, but only thanks to compiler writers. at one point committee went all-out enforcing their lifetime model, making bit_cast not an option. If your code accesses same data using different types, you are spelunking ruins with snake pits and lava. more and more stuff needs magic support code in std::, making no-lib code less and less possible (it used to be that with no-rtti and no-exceptions, you could use all c++ features and only needed cxa_at_exit, operator delete, and few other little things. NOT ANY MORE).

On one hand, you have consteval and stuff, letting you FINALLY initialize data at compile time (hey, 20 years late but still!)

on other hand, it is done in most non-debuggable way possible. try setting breakpoint or adding print to constexpr function that causes your requires clause to fail...

so no, newer C++ the language is not possible to use for low level work. The dialects that compiler makers support are. We will see for how long
