I've read a reasonable chunk of that thread. The things that struck me were: 1. It's very confused between a number of proposals, making it extremely hard to identify which arguments apply to a simple Scripts->bin renaming (both at the time, and now in hindsight). 2. As far as I can see, on the subject of Scripts->bin, the thread from python-dev was essentially neutral, nobody could see a benefit that justified the cost. (PEP 453 doesn't say much on the benefits, either, FWIW). By the way, PEP 453 is actually misleading in one respect, distutils (and setuptools) installs scripts to PythonXY\Scripts (which is created on first use, not at install time), it's only the core-supplied scripts that go into PythonXY\Tools\Scripts. Personally, I'd like to see a better justification than "to improve consistency". I'd also like the point that the *existing* Scripts directory (managed by distutils/setuptools installs) will have the contents of Tools/Scripts dumped into it made explicit and discussed. (For example, there's a diff.py in Tools/Scripts. Will the new bin directory be put at the start or end of PATH? If I have .py in my PATHEXT that matters to me, as diff.py could end up overriding my existing diff.exe). And I'd like to see the actual patch that implements the Scripts->bin change - I suspect that it would benefit from careful review. Overall, I'm -0 on the proposal, The arguments either way are weak, and I don't see why backward compatibility is being ignored quite so calmly. It is entirely peripheral to the PEP as far as I can see, and not worth including in there. But once again, that's separate from my point here, which is that I need to collect information on whether virtualenv users will be impacted by the corresponding change in virtualenv. I suggest that virtualenv comments remain on distutils-sig, but comments on the PEP proposal to rename Scripts be redirected to python-dev which is where the PEP discussion is taking place. I *haven't* cross-posted to python-dev, because that would only start a 2-list thread, but can people redirect appropriately any responses?
