The new "vertical bar" syntax was proposed recently, and has gotten almost unanimously positive feedback. In particular, of 17 responses to the syntax, only one has been negative (see table, below). I'm including both of the following variants: |classmethod |accepts(int, int) |returns(float) def foo(arg1, arg2): ... def foo(arg1, arg2): |classmethod |accepts(int, int) |returns(float) ... (I prefer the second, but would be happy with either.) The one negative comment was that "|" can look similar to "I" or "l", depending on the font; but it's only an issue for some fonts, and it should be largely mitigated by syntax-highlighting. So I wanted to see if anyone has anything negative to say about this syntax (or one of its variants). If possible, please respond by updating the wiki, rather than by email. This syntax is listed under H (pre-def) and E2 (post-def). You will need to sign in before you can edit the wiki. Wiki: <http://www.python.org/cgi-bin/moinmoin/PythonDecorators>

-1. I think vbar-before is an extremely hard syntax to read, and vbar-after is extremely misleading (but I don't like where docstrings are, either). Wiki updated.
