Do you mean "expected" or "unexpected" exceptions? I.e. exceptions you use for application flow, or ones that are as a result of internal bugs.
Sorry, I should have been more clear. I'm developing an API, and I'm mostly looking to handle what you call expected exceptions. The PSGI HTTPExceptions module seems to be along the lines of what I'm looking for. The idea is to have a single, simple way from anywhere in the codebase to return, say, an HTTP 400 error (wrapped in JSON) to the API user. Some authentication util methods would probably also like to return a 401 or 403 for certain conditions. So, ideally, I'd rather not have anything grab and rethrow exceptions as strings (as seems to happen now in a few places in the Dancer2 codebase). I guess I'm really looking for a way to avoid or circumvent what seems to be the default Dancer exception handling behavior. -- Paul
