[Python.NET] Is there a chance to imprive Python for .net to let "System.Windows.Forms.Form().Controls" be indexable?

Very interesting;
Apparently, Microsoft doesn't think that it is a useful thing to index 
directly into a System.Windows.Forms.Control.ControlCollection Class.
The collection is still iterable in versions above 2.0, but the class no 
longer supports indexing. So:

 >>> print form.Controls[0]         # works in pythondotnet built on 
.NET 2.0 on prior.
<System.Windows.Forms.Button object at 0xaa8bc6c>

for ctrl in form.Controls:
     print ctrl    # works in .NET 3.0 and above.

and you'll see that all ICollection and IList properties have been removed.

Reasons why are a good topic for future discussion.
