I think these are two very strong arguments in favour.
python.exe isn't anything like the interactive shell that people use on
a day to day basis and simply stating that it is doesn't mean that it is.
Just to clarify, when I say command interpreter I wasn't necessarily
implying interactive -- just as nobody (I hope) attempts to use /bin/sh
in its pure, restricted posix mode, as their native interactive shell.
[side note: IPython, an interactive shell-like python environment -- is
really cool]. I just meant that python /interprets/ /commands/
(possibly -- usually -- in a script).
For ActivePython, you'll see win32 shortcuts with target:
<path-to-active>/python.exe <some script>
If cygwin's 'python' is a copy of version x.y, then cygwin users can do
the same: have win32 shortcuts with target:
<path-to-cygwin>/python.exe <some script>
(Now, ActivePython sometimes cheats: it associates .py with itself, and
often win32 pythoners will just give their scripts a name with that
extension. And obviously, windows doesn't, itself, recognize shbang lines)
Granted, there are 57 other, different solutions that don't require
cygwin's 'python' to be a copy, like invoke version x.y directly from
the shortcut:
<path-to-cygwin>/python2.5 <some script>
or cgf's use-bash-first:
<path-to-cygwin>/bash.exe python <some script>
or use-bash-first and rely on shbang:
<path-to-cygwin>/bash.exe <some script with #!/bin/python>
But if cygwin does the copy thing, we'd be following the 'principle of
least surprise' for ActivePython folks (AP is, after all, the other
major python implementation on win32; IronPython is coming along nicely,
tho).
'invoke from native win32' means 'from a shortcut OR cmd window' not
just 'from a cmd window'
