// Test that identifiers which are used explicitly in the grammar but are

// The identifiers listed below are mentioned in the grammar, but none of

// be used as a library prefix; this test puts such prefixes in wrong
// locations to verify that this is being handled. Here are the 'known'
// identifiers: `async`, `await`, `hide`, `of`, `on`, `show`, `sync`, `yield`.
