// `Wrapper::sentry` and `sentry` should be emitted as `Wrapper_sentry` and
// `sentry` respectively, but instead `Wrapper::sentry` is named just `sentry`
// which leads to compilation errors.
//
// Note: if there is no namespace, then we don't run into problems. Similarly,
// making the `Wrapper::sentry` definition inline in `Wrapper`, rather than
// declared inline with an out of line definition, makes the problem go away as
// well.
