Now, most of this code is more or less crap, but I do suggest taking a look at my first stab at a RPython interpreter for Clojure https://github.com/halgari/clj-pypy IIRC, the target complied okay, and you could run the code in scratchspace.clj. Basically I got to the point where I realized that if I had lisp macros, I could write RPython code way faster. Half of the structures in Clojure follow this pattern: class Foo(object): def __init__(self, foo bar, baz): self.foo = foo self.bar = bar self.baz = baz def addBarBaz(self): return bar + baz I could write that for that, or, in Clojure I could write myself a macro and just do: (deftype Foo [foo bar baz] (addBarBaz[self] (+ bar baz))) So basically I've found that I can write the same code in the following languages with this line ratio: Clojure: 1 Python: 3 Java: 6 This is the reason I shelved the RPython idea. If I want to dramatically re-define how types are handled in Clojure-py all I have to do is re-write a single macro. <over generalization> "Why write a jit when you can have RPython do it for you?" "Why write a typesystem, when you can have Clojure macros do it for you?" </over generalization> Timothy -- “One of the main causes of the fall of the Roman Empire was that–lacking zero–they had no way to indicate successful termination of their C programs.” (Robert Firth) _______________________________________________ pypy-dev mailing list pypy-dev@python.org http://mail.python.org/mailman/listinfo/pypy-dev
