As a library author you don't know what the application is 
interested in.

Anyway, they are working on retaining context, so the Rust 
developers apparently see this as being an issue.

If you can only use "?" in one location without loosing context 
that basically establishes it as being the quick hack it looks 
like (by reading the docs).
