Sorry for the misinformation: the test does NOT work with the comtypes 0.4.0
code
and the above changes. This small patch is required so that the comtypes
property
setters accept multi parameters:

Well, getting the property by calling the 'Value' works:
...Range["A1:B2].Value()
This functionality was probably implemented by taking win32com as example,
but I am no longer sure that I like it. But it will probably stay for
compatibility.
