Still cool, but I would definitely ease back the first claim.
I was going to say it does make me wonder how much a pain a direct processor like this would be in terms of having to constantly update it to adapt to the new syntax/semantics everytime there's a new release.
Also - are there any processors made to mimic ASTs directly? I figure a Lisp machine does something like that, but not quite... Though I've never even thought to look at how that worked on the hardware side.
EDIT: I'm not sure AST is the correct concept, exactly, but something akin to that... Like building a physical structure of the tree and process it like an interpreter would. I think something like that would require like a real-time self-programming FPGA?
