I would describe Rust's error handling crisis more as: 1. I'll just handle all of the errors by having my functions return Result<T, E> where E is some type that encapsulates all of different error conditions that can happen in my function. 2. Function one returns Result<T1, E1> and function two returns Result<T2, E2>. What type do I use for a function that calls both and just uses `?` to defer handling on errors from either function? Guess I either have to use Box<Error> and do a bunch of ugly downcasting whenever I want to handle an error or I have to write a bunch of code to define another error type E3 which combines E1 and E2 and I have to implement From<E1> and From<E2> so now I have more code just for defining error types and conversions than I have for actually doing anything. 3. Create complicated macros like error_chain[1] or failure[2] to try to cut down on boilerplate in #2.
