First time I hear about checked exceptions. How do you use them ? Are you forced to handle them explicitly ? Is the handling checked at compile time ?

Checked exceptions require a function to declare the exceptions it can throw. The caller function must then catch and handle the exception, or the exception would bubble up a level, in which case the caller must also include that exception among the exceptions it declares that it can throw. I don’t know if C++ does this, but Java/C# do. It sounds exactly like Rust’s system except with different syntax.
