I am quite new in Python, and I do my first suggestions. (One time
I should begin)

If there is a general agreement about what to do to wrap a decorator,
why no use the following syntax

@decorator
def trace(f):
    def do_trace(*args):
        print "invoking", f.__name__, args
        return f(*args)
    return do_trace

I would prefer it because it explain what the method do
instead of how it implement it.
Generally speaking, I believe the decarators should
be very expressive, just because even if it is not
a part of  the language, it's a kind of new syntax.
For the same reason, Python should incorporate
just a reduce set of decorators.
