Dear Ruby fans,
A common Lisp exercise is to write a Lisp program that writes its own
source code to standard output. Reading from a source file is not
permitted.
This leads one to wonder: what is the smallest and / or most elegant
Ruby program that writes its own source code to standard output? As
with Lisp, reading from a file is not permitted. Given the nature of
the language, this problem should should have a lot of interesting
solutions.
This is called a Quine, right? I can't beat Ryan Davis', so I'll just
link to it.

My favorite Ruby quine is
<code>
DATA.rewind
STDOUT.write(DATA.read)
__END__
</code>

There's a whole page of Ruby quines (including 2 of my own) in the
rubygarden wiki: http://rubygarden.org/Ruby/page/show/RubyQuines

I did one in ERb, too:

Very nice. I looked up "DATA" in the pickaxe and found that I had
previously highlighted it - must've been a long time ago. Here's a
rewindless version
puts DATA.read * 2
__END__
puts DATA.read * 2
__END__
