C++ ain't my favorite language, but by George it has the `[[nodiscard]]` function decorator and I have used *so many* other languages that should either have that decorator or should have semantics that don't require that decorator... Instead, the average case for languages I use is "If you call a function and ignore its return value completely, sucks to suck."

In Go, in particular, the easiest way to introduce bugs to your code is to call a function that returns an error and then just ignore the return value.
