That's a good one. It reflects lots of discussions Alon and others, 
including yours truly, have had over the years.

The important point is not just "bytecode isn't everything" -- also 
important are trade-offs in have two syntaxes, something that came up 
here on es-discuss long ago. Here's a post from Maciej of Apple:

https://mail.mozilla.org/pipermail/es-discuss/2009-December/010238.html

The topic then was AST encoding, not something people think of as 
"bytecode". Michael Franz at UCI and Ben Livshits at MSR had worked on 
arithmetic coding of ASTs (avoids need for verification).

The topic is deep and memes die hard. I think Alon's post is the right 
thought-piece; anyone have others?
