Quining has a long history - if you haven't heard of it, click the tag and read up a little on it.
Output an infinite series of
1s (with no other spacing [newlines, spaces, etc.]) UNTIL SIGINT (typically CTRL-C) is called. When it is called, output the program source.
- It must be a valid quine:
- No reading source from the disk.
- See all other standard loopholes relating to quines.
- You may use any language.
- As this is a code golf, the shortest answer wins!
