zig-lang and vlang have special handling and function markers for exceptions or
errors, they are wrapped in an option type and there is some language support
to make it concise. I think it's a nice innovation. The main idea is that
exceptions are not some subtle invisible thing that bubbles up until maybe
someone catches it. the compiler sees the errors and requires you to handle
them, and make a decision where to handle them. Nim has the raises pragma,
which has a lot of potential when we're talking about safe, maintainable, error
free programming. It also reduces the programmer stress for critical code that
just has to be bug-free. Basically reduces the possible ways that the program
can fail or produce errors or bad data.
