Thank you for criticism and tasks examples.
But I still think it isn't such a bad idea. Because if somebody get excited
about some language (even if it is based on "promotional" cases) and he
learns this language more by himself then it's great. I don't think
somebody will judge about whole language by few tasks. He may get
interested or dislike the language, but I doubt there will be silver bullet
cult based on few tasks.
By shopping language I mean choosing some new fun language to learn, not to
solve particular practical task.
