Absolutely. I have no problem with mistakes being made. It's setting 
them in stone that's the trouble.

The only person in a position to do (1) is Jack, which is unfair on 
both Jack and any third-party who might otherwise fix it themselves, 
(2) is just ducking the issue and (3) is obviously a non-option.

(4) Remove the current implementation from the standard library.

In OSA.so's case this could be done completely painlessly as it's not 
like anyone's actually using it. Older material may require more 
delicate extraction and a proper repackaging to allow separate 
installation, but it's still perfectly doable.

Umm, no, I don't. I've been using file specs to refer to non-existent 
files for years. It was the standard solution in OS9, and while 
fileURL is supposed to supercede it in OS X it persists for legacy 
reasons and because fileURL support still isn't quite what it should 
be. And I've really no desire to start kludging up Python; I've 
already endured enough kludges in AppleScript to last a lifetime and 
the whole point of shifting to Python was to get away from all that

Why? All it means users have to do two installs instead of one to get 
set up which is no huge effort, and in practice the MacPython 
installer could bundle and run a recent copy of the MacAll installer 
for convenience. And once all this stuff is out the standard library 
it's free to be working on without the onerous scheduling 
restrictions and personnel bottleneck that comes from being locked up 
in the standard library. Have I missed something?
