Before we use a decorator to do something, we can instead use it to do nothing.
def annotate(*args, **kwargs):
    def __decor(func):
        return func
    return __decor
This will allow us to use the decorator to write comment-like annotations, only that they are much easier to search for than comments when using an IDE or regex.
@annotate(endpoint='/', name='index')
def index():
    return "Hello, world!"
It can be later improved upon, as we can at any time rewrite it into a functional decorator.
