specify the type for function signatures (mentioned in this email

also very useful if you kind of gave an example how the mini language

A solid start is to read the following documentation:

as we discussed on the sprint I have now experimented with an SSE/AVX

I ran some small measurements on it:

sorry about the lengthy email, but you asked for details :)

Hi,
the jit log currently is only functional with the vmprof platform.
There was this idea of a command line tool to inspect, but it is not yet

$ python -m jitlog --upload

Hello,
I have prepared an alpha release for the python 3.3 branching from the

information at the calls

Hi there,

So I guess it is feasible :). My advice would be to build the VM and
make some baby steps in the test environment. This might sound weird,

Hi,
the answer to your question very much depends on your python experience.
A good place to start is the bug tracker [1] and (potentially much more
interesting) the documentation[2][3].
Most of the time smaller tasks include adding features in the python 3
branch of pypy (py3k or py3.3).

Do you think that it would be worth trying?
