It seems to me that we've had decorators all along (if we expand the
definition a little), for example __metaclass__ sure looks like a class
decorator. So how about...
def func(arg1, arg2):
"""Docstring goes here, as normal."""
__version__ = 'Added in 2.4'
__returns__ = None
# function body goes here
def returns(func, *args):
"""Docstring for 'returns' decorator."""
__decorator__ = True
# body of decorator goes here
