The out parameters are the trickiest part. The solution we are working
on will hopefully address that problem. If not (or if it is not a pretty
one for the out parameters) we will keep looking. The ultimate goal
is to achieve state where we can call any particular method without
ambiguity, and also do that within the limitations of Python syntax
(i.e. Python code object.method(out x) ... is not really an option)

We are actually going to do something quite similar. Since I am just
beginning to write the code for the method 'pinpointing', I'll have
some results later today or after the weekend. Then I'll send along

The kwargs support you are seeing is to enable setting properties at
construction time. For example:
from System.Windows.Forms import *
f = Form(Text = "Hello") # <<= the call
I agree with you that the kwargs on reflected methods are not as useful
as when calling Python methods. For C# programmers that is. Visual Basic
programmer could disagree since VB supports passing arguments by name:
Public Class Class1
Public Sub Test(ByVal name As String, ByVal age As Integer)
Public Sub X()
You are therefore bringing a very interesting point with the kwargs
for reflected methods and we should definitely give it a thought.
