short

Just finished reading this blog post: http://www.skorks.com/2010/03/an-interview-question-that-prints-out-its-own-source-code-in-ruby/

In it, the author argues the case for using a quine as an interview question. I'm not sure I agree but thats not what this question is about.

He goes on to construct a quine in Ruby and refactor it to make it shorter. He then challenges the reader to try to make it even shorter.

I played around with it for a while and came up with the following:

s="s=;puts s[0,2]+34.chr+s+34.chr+s[2,36]";puts s[0,2]+34.chr+s+34.chr+s[2,36]

This is the first time I have ever attempted a quine and I can't figure out how to make it any shorter.

What is the shortest Ruby quine you can come up with? Please post an explanation if your implementation requires it.

I have created a turing-complete programming language (already proven) so it must be possible to write a quine for it, right?
