Trait problem::ProblemWhile

pub trait ProblemWhile<O> {
    fn problem_while(
        self, 
        msg: impl Display
    ) -> Result<O, Problem>;
    fn problem_while_with<F, M>(self, msg: F) -> Result<O, Problem>
    where

}

Add context to Result with Problem or that can be implicitly mapped to one
