// `deno test --doc` tries to convert the example code snippets into pseudo
// test files in a way that all the exported items are available without
// explicit import statements. Therefore, in the test code, you don't have to
// write like `import { add } from "./main.ts";`.
// However, this automatic import resolution might conflict with other
// explicitly declared identifiers in the test code you write. This spec test
// makes sure that such cases will not cause any issues - explicit identifiers
// take precedence.
