What syntax "should have been obvious from the beginning"? I always felt like most things in Rust are around as simple as they could be, for the things the language is trying to do.
type TestResult = Result<(), Box<dyn std::error::Error>>
is not obvious nor simple and makes a joke of the claim that Rust is simpler than C++ in error handling. Damn, I prefer straightforward C++ exceptions after seeing stuff like this.
