In the case of just one decorator, the dictionary could be omitted.  The
decorator function itself could have an annotation flagging it as a
consumer of annotations, so that would make it easy to check if there
was more than one.  In your example above, you'd also want a @typing
decorator.  

In those particular cases, the decorators don't even need the annotation
feature:

@cmdline(name="Name of user to add", password="Password for the new user")
@typing(name=str, password=str)
def adduser(user, password):
    """Add a new user"""
    ...
