On re-reading what I wrote, I don't think I actually clarified the point I was 
trying to make originally.

My point wasn't that I desparately need @-syntax for class decorators (I 
don't), or see it as inherantly superior in some way.  It's much simpler than 
that:  I just want to be able to use the same syntax for a group of use cases 
regardless of whether the target is a function or a class.

This fits into the nice-to-have category for me, since the use case can be the 
same regardless of whether I'm decorating a class or a function.  (I will 
note that when this use case applies to a function, it's usually a 
module-level function I'm decorating rather than a method.)

My other example, the zope.formlib example, has only ever involved a single 
decorator, and is always a method.  It could conceivably be applied to a 
nested class without much of a stretch, however.
