Having only one method keeps the API simple. Also, the addspec() approach
allows the user to choose between single and multiple lines.
BTW, addspec() could be made completely general by supporting all possible
keywords at once:
def addspec(**kwds):
def decorator(func):
func.__dict__.update(kwds)
return func
return decorator
With an open definition like that, users can specify new attributes with less
effort.
