I think so. There are some thingamabobs in there too. :)
I think we'll see at least a syntax tree, a bytecode stream, and an optree
in perl 6, depending on where you look. That's still sort of up in the air,
though. (We might see machine code too, if I can convince myself that it
can be done portably)
