If we're using Zope 3 as an example, I personally find that:
class Foo:
"""Docstring here, blah blah blah
"""
implements(IFoo)
is easier to read than:
@implements(IFoo)
class Foo:
"""Docstring here, blah blah blah
"""
Yeah, but in the first case implements(IFoo) has to do dirty hacks involving sys.getframe(), so you win in once place but lose in the other one.
