5990	permalink() works a little different from {% url %}	johnfractal@…	nobody	"I'v wasted one whole night with this problem, and I got the ""bug"", just here:

{{{

    parameters returned by the decorated function ""func"".

    ""func"" should be a function that returns a tuple in one of the

        (viewname, viewargs, viewkwargs)

The implement of {% url %} is more convenient to use, and I hope permalink() would be as convenient as {% url %}.
