@davecheney, I’m mostly thinking out loud here, and haven’t thought as far as an API yet, but I’m wondering if a cascading priority makes sense:
- If the caller chooses to render the error with or without a stack trace explicitly, that is always honored.
- If the caller uses default error rendering, but the error itself (based on options when the error was created) prefers to be rendered with or without a stack trace explicitly, that is how the error is rendered.
- If neither the caller nor the error specify if they want a stack trace, a global default, (similar to #96 / #97) determines if the error renders a stack trace.
As I indicated above, these are just ideas I had reviewing old PRs. I’d be interested to hear your opinions.

Thank you for your comment. My position has not changed since my last comment.

I've just decided to use %+v
if debugging is enabled. This works for me since everything goes through a single CLI library, but maybe others want this. Closing.
