I much prefer this to @decorator.  In addition to the advantages that
Shalabh gives:

 + It doesn't break Leo, IPython, or any other tool that uses @ as a
   special character.

 + The association with pipes makes some sense: "take this thing and pass
   it through that thing to get a modified thing".

Perhaps someone with write access to the Wiki page at
http://www.python.org/moin/PythonDecorators could add this idea there?
It would be a shame if it got lost in the high-volume traffic here on
python-dev.  Unless there's some overwhelming technical reason why reusing
the '|' character isn't possible, of course.
