Pardon my obviously amateur question, but would you build an AST-based compiler/parser to generate the same (minus the ones you intend to eliminate) opcodes to run on the VM in the same way as the current compiler does? Would tools like XDebug, APC, Zend PHP encoder (or whatever that's called this week), etc. be compatible out of the box, or would changes need to be made to them? Also, here is a potential starting point if you're less allergic to OCaml than I am: https://github.com/facebook/pfff S
