Tell Me about yourself Your task is to write a self referential program similar to a quine. The objective is to write a program that will generally print to stdout twice whatever the input is. But when it receives the input of "Tell me about your source" it should output its source (like a quine). Also if it receives the query "tell me about your length". It should output its length in utf-8 characters. Like always all standard loopholes are disabled. This is code golf in any language of your choosing.
