(I'm thinking the dev-mode-error-handler is something I probably could/should extract, once it's polished up. Not sure if it should live in tide or as an external crate, since it's somewhat opinionated, but assumedly opt-in) |

If this turns out to have meaningful performance implications, we could feature flag this or just do it conditionally when debug_assertions are on.
This combines well with #212 to allow for this sort of development-mode error handler in tide:
