Fixed in r17210.
e entries for "Get python bytecode translator done"
and "Pass the pie-thon test suite". Are these still active
waypoints on the roadmap, or should we remove them?

Well, we were shooting for an end-of-August release, but needless to
say that's not happened. Both Leo and my translators were reasonably
near completion, and need to be pushed that final bit of the way.
Neither of us have the time, so... Anyone want to take a shot? Leo's
builds faster code but
Fixed a bug in the damn thing (that I'd introduced) and fixed the tests to
actually test properly, including both a Python 2.2 and 2.3 format
bytecode file in the archive.
Rather than mail the thing to people *again* I've just stuck it up for web
snagging.

The last rev of Python::Bytecode is up and available for poking at.
http://www.sidhe.org/~dan/Python-Bytecode-2.3.tar.gz if you want it.
Handles multiple code objects in a file now (woo!) as well as actually
supporting Python 2.1 and 2.2. I think. Tests would be in order, but I
haven't act

After spending a couple of hours looking at Python::Bytecode and the
Python source, I decided I didn't like the module. So I wrote my own.
I decided Bytecode::Python would work nicely for the name, though it's a
bit close to the namespace. I basically redesigned it, so it should be
Still a bit lacking, 'specially in the documentation department, but I've
got a version that sucks much less than it did, and is possibly even
correct. (Go figure. Surprised me, too... :)

Maybe you could give me an example of some input and the correct output?

Wouldn't something this do what is desired? I'm just guessing, though.

My experiments[1] show that the latter should be doable, the more because

For ops that take a parameter, the parameter name is in lower

Or at least I can't get it going. Fixing it's a project for the
interested. (I'd ask Simon but, well, he doesn't do that stuff any
more)
