[IronPython] COM Object Issue

[Zaur Shibzoukhov]

I just discovered strange thing with COM (IP 2.0):

D:\Downloads\IronPython-2.0-Bin\IronPython-2.0>ipy.exe
-X:ExceptionDetail -X:ShowClrExceptions
IronPython 2.0 (2.0.0.0) on .NET 2.0.50727.1433
Type "help", "copyright", "credits" or "license" for more information.
>>> import System
>>> wt=System.Type.GetTypeFromProgID("Word.Application")
>>> wa=System.Activator.CreateInstance(wt)
>>> wa.Documents.Add()
<Microsoft.Office.Interop.Word.DocumentClass (_Document) object at
0x000000000000002B>
>>> wa.Documents[1]
Error while invoking Item.

>>> wa.Documents[None,1]
<Microsoft.Office.Interop.Word.DocumentClass (_Document) object at
0x000000000000002B>
>>> wa.Documents[100000000000000000000,1]
<Microsoft.Office.Interop.Word.DocumentClass (_Document) object at
0x000000000000002B>

It looks like IP's wa.Documents indexer make wrong call of .Item.
