I have a decorator that adds an attribute to the decorated function:

I think 5 is clearly wrong, 4 is too difficult, and 3 seems pointless. So I
think either 1 or 2 is the right thing to do.
Thoughts?
It depends if the attribute "instrument" is part of the public interface.
If not, just find a different name unlikely to clash with an existing
one *and* raise an exception if it does ever happen anyway.
If the attribute is part of the public interface but you re using the
code only internally then 1/ raise an exception, otherwise I don't know :o)
It seems to me that over-writing silently (or not) may lead to bugs
difficult to spot.
