These lines:

The .wrapped attribute has the wrapped object, so you're printing out
the thing that would be in x if you weren't using the decorator. Since
that's a subclass of list and doesn't change __str__ or __repr__, it
prints out like a list.

Tip: If you're not sure what line produces what output, tag them all.
Instead of print(x.wrapped), put print(1,x.wrapped), and have a
different number on every line of output. Then you'll easily see which
is which.
