win32com map attributes to methods

[jj]

Hi, I am trying to map attributes in COM object to methods, so when
attribute (for example: Expires) is set a "set_Expires" method will be
called, and when the attribute is read a method prefixed with "get_"
(get_Expires) method should be called.

I think I  am on a good path, because my example is working 50%.
get_Expires is called when reading attr., but set_Expires is never called.
their implementation is so similar and simple, that there must be a simple
solution.

Thanks for your help
