It's really about time I added some decimal-unary conversion feature to Retina...

 <empty>

Where `<empty>` represents a trailing empty line. For testing, you can run the above code with the `-s`, in which case the output will be separated by `#` instead of newlines. To get the valid (and counted) program, you should put each line in a separate source file, and replace with `#`s with literal newlines.

For comparison with the other Retina answer, if I omitted the unary-to-decimal conversion, this would be only 72 bytes.

I'll add an explanation when I'm done golfing the conversion code.
