I added another `#\n` so that retina would cooperate. Here's how it works:

`#` redefines `v` to push `0`, the default TOS. Then, it negates the TOS (<code>\`</code>), pushes 1 and 6, the character of `<`, pushes 6 again, and mirrors upwards with `/`, colliding with the other <code>\`</code>, which negates the 6. Then, it hits the `<`, pushes `J` (base 36 for 19), then outputs it as a `n`umber, finally terminating (`~`).


Escapes in between `o` and `|`; `2` and <code>\`</code>; and `#` and `g`.
