Not quite ready to show this off on Twitter yet, but:

- The Sire bootstrap is down to 2500 LOC.

- The compiler can quine with just four jets: Add, Sub, Mul, Div.

- The compiler exe, serialized and compressed is 13k.

- The disassembled exe pretty prints as 1500 LOC.

We will soon have a demo of this, that you can run in the browser, using a tiny PLAN runtime written in C.
