//! A field that does not exist is reported by the macro, listing the fields the user declared and
//! never the `OhnoCore` injected by `#[ohno::error]`.
//!
//! The two spellings reach that report by different routes and are spanned accordingly: a named
//! placeholder is caught while parsing the template, so it is spanned at the template, while a
//! positional argument is caught while validating the argument's root, so it is spanned at the
//! offending term rather than at the whole attribute.
