// This is testing whether `#[inline]` signals an error or warning
// when put in "weird" places.
//
// (This file sits on its own because it actually signals an error,
// which would mess up the treatment of other cases in
// issue-43106-gating-of-builtin-attrs.rs)

// Crate-level is accepted, though it is almost certainly unused?
