I just anted to rewrite those "real-life-looking" examples with my proposed
'%' syntax:

def foo() % (classmethod, accepts(int,int), returns(float),):

or formatted:

def foo() % (
   classmethod,
   accepts(int,int),
   returns(float),):

Or it can be done the this way:

def foo():
   ...

foo %= (classmethod, accepts(int,int), returns(float),)

The operation could be called "decorative apply", if the LHS
has __call__ attribute. Just a new form of % operation with
special syntax for "def" operator.
