Cool.
I hope others can review, and you should ask Barry if this is okay for beta3.

I hope this patch is simple enough for you:

Positional arguments after the *args are explicitly disallowed:
f(1, *[2, 3], 4, z=5)
The syntax could make sense, but this would require more changes in
the compiler,
to properly order the parameters.
Are you saying that after the above Grammar change, the code generator
already does the right thing for Raymond's code?
Yes! the ast builder simply collects items from the parenthesized sequence,
and does not care about the ordering - except for an explicit
"non-keyword arg after keyword arg".
Then I say go for it
-- but please do add new unit tests.
Of course -- I was just requesting approval.
I am working on a documentation patch as well, and filed
