Guido:

Just look at it when either the list of decorators or the argument list doesn't fit on one line:

You don't have to format it quite that badly.

def longMethodNameForEffect(longArgumentOne=None, 
                            longArgumentTwo=42) \
    [staticmethod,
     funcattrs(grammar="'@' dotted_name [ '(' [arglist] ')' ]",
               status="experimental",
               author="BDFL")]:

If you can arrange for the '[' to appear immediately before the first decorator, I think it makes it a lot easier to recognise the construct for what it is.

I also think that's a rather untypical decorator argument you've used there, being full of spaces, brackets and other confounding characters. That sort of thing is going to look confusing in any context, whether function decorators are involved or not.

Perhaps someone can post some real-life use cases written with this syntax, so we can see what it would really look like in typical use, as opposed to made-up worst-case examples?
