Err(_) => {

Adding a hack to panic on the error shows me this:

error: custom attribute panicked

   = help: message: Error finding rapace crate: Could not read `E:\rs\rapace-shit\Cargo.toml`: parse error: Operation failed on shape PanicStrategy: No variant found with the given name

It turns out I'm using the latest panic feature in nightly, but it wasn't catched up in facet-cargo-toml, so I filed bearcove/facet-cargo-toml#4
