I thought the ability to do that was being removed in py3?
throwing some ideas around, for all examples arg1 and arg2 would be
positional only
def test(<arg1, arg2>, arg3, *arg4):
...
It's ok, since it clearly groups the positional only args, but the
parser might not be able to handle this.
def test(|arg1, |arg2, arg3, *, arg4):
...
Simple, but inelegant. In just looking at the code it seems wrong.
def test(arg1, arg2, |, arg3, *, arg4):
...
I like this idea better, use the pipe as a separator for positional
only, and normal arguments.
