`@` actually behaves as an "include" operation (i.e. the contents of the relative file are tokenized into more response file args). It will fail if a directory is passed because it is only used by `FileSystem::getBufferForFile`.

The `<@>` operation I am proposing does not perform any file load and simply expands to the base path as the function already knows it.
