I am once again reminded how much of a clusterfuck C++ as a whole is.

They recently (C++17) added this cool new attribute called nodiscard.
You can put it on a function like this

[[nodiscard]] bool writeMessage(...)

and the compiler will check if the returned value was discarded or not, and give a warning accordingly.
Pretty neat if you're returning an error code and you want to enforce that it gets checked, right?

Except it doesn't work in template classes.
It just doesn't do anything there.
