Mike Gerwitz f218c452b9 tamer: iter::trip: Flatten Result ... The `*_iter_while_ok` functions now compose like monads, flattening `Result` at each step and drastically simplifying handling of error types. This also removes the bunch of `?`s at the end of the expression, and allows me to use `?` within the callback itself. I had originally not used `Result` as the return type of the callback because I was not entirely sure how I was going to use them, but it's now clear that I _always_ use `Result` as the return type, and so there's no use in trying to be too accommodating; it can always change in the future. This is desirable not just for cleanup, but because trying to refactor `asg_builder` into a pair of `Parser`s is really messy to chain without flattening, especially given some state that has to leak temporarily to the caller. More on that in a future commit. DEV-11864		2022-05-20 16:08:16 -04:00
