The code example for 'property' in the online documentation appears to
have several syntax errors.

In the class C, the functions getx, setx, and delx all refer to '_x',
but __init__ assigns '__x'.  In other words, single underscores were
used where double underscores were intended (or vice versa?).

NOTE: I was unsure what "Type" of issue this was based on the provided
list.  I chose "compile error" because it seemed to be the best fit.
