Below are my answers the issues raise by Nick on pydev in response to
Todd's initial version, posted there before moving to python-ideas.

I added this to the summary -- everything in idlelib/*.

"IDLE is primarily used as an application that ships with Python,
rather than as a library module used to build Python applications,
that's why it is OK for a different standard to apply".
Todd added something like this and I reworded to say much the same thing.

I know nothing about Linux distros and so that is not a motivating point
for me. But if given a sentence that you (Nick) consider valid, and a
suggestion of where to put it, I will certainly add it.

I removed much of the discussion about testing as the PEP does not
propose to change the rules about test before commit. I already opened
an issue about improving automatic testing.

The alternative to automatic testing is testing by hand rather than no
testing. I mentioned that backporting is extra work for developers, that
this extra work might mean not backporting, and that both are true
regardless of how an improvement might be classified.
IDLE's current tests are all within /idlelib, just as tkinter tests live
within /tkinter. If this PEP is approved, new tests can be backported
without controversy. My understanding is that that is not true for
coverage tests for other modules. Backporting a new test_idle.py in
Lib/test, similar to test_tkinter.py, is not covered by this PEP.
