// Tests the backwards compatibility hack added for certain macros
// When an attribute macro named `proc_macro_hack` or `wasm_bindgen`
// has an `NtIdent` named `$name`, we pass a plain `Ident` token in
// place of a `None`-delimited group. This allows us to maintain
// backwards compatibility for older versions of these crates.
