So what I'm gathering (I'm still trying to grok) is that clojure-metal is an approach that somewhat parallels PyPy, except in Clojure, and except that instead of defining a type-inferrable subset RClojure, you instead define an internal DSL via mjolnir that allows you to specify the types within Clojure? But unlike RPython which can run as a CPython program without any special handling, the mjolnir DSL is only intended to be run as a bytecode generator. Is that about right? I'm wondering, if the intention is to parallel PyPy, but use Clojure instead, would a more generic thing to do be to start with PyPy toolchain, but abstract it so that the input is not RPython, but rather any type-inferrable language and a corresponding AST generator, and make it so that PyPy is no longer Python-specific at all? (Well except the toolchain code would still be python, but that's just an implementation detail). So from that toolchain it'd be possible to define RuRu, CloClo, maybe dynamic MLML or CC, or of course cross-version CloML or RuC? Or is the PyPy toolchain still too specific to "Python-like" languages that it'd produce something suboptimal for Clojure and other languages?
