contained in [[scala.reflect.api.Universe Universe]]s. Typically all processing happens + * within a single `Universe` (e.g. a compile-time macro `Universe` or a runtime reflection `Universe`), but sometimes + * there is a need to migrate artifacts from one `Universe` to another. For example, runtime compilation works by + * importing runtime reflection trees into a runtime compiler universe, compiling the importees and exporting the + * result back. + * + * Reflection artifacts are firmly grounded in their `Universe`s, which is reflected by the fact that types of artifacts + * from different universes are not compatible. By using `Importer`s, however, they be imported from one universe + * into another. For example, to import `foo.bar.Baz` from the source `Universe` to the target `Universe`, + * an importer will first check whether the entire owner chain exists in the target `Universe`. + * If it does, then nothing else will be done. Otherwise, the importer will recreate the entire owner chain + * and will import the corresponding type signatures into the target `Universe`. + * + * Since importers match `Symbol` tables of the source and the target `Universe`s using plain string names, + * it is programmer's responsibility to make sure that imports don't distort semantics, e.g., that + * `foo.bar.Baz` in the source `Universe` means the same that `foo.bar.Baz` does in the target `Universe`. + * + * === Example === + * + * Here's how one might implement a macro that performs compile-time evaluation of its argument
