For kwargs you need to decorate the function w/ a ParamDictionary attribute
such as:
public void __init__(CodeContext/*!*/ context, object o, [ParamDictionary]
IAttributesCollection kwArgs)
For __getattr__ IronPython will recognize a special name "GetBoundMember"
method such as:
using System;
using System.Runtime.CompilerServices;
public class Foo {
[SpecialName]
public object GetBoundMember (string name) {
return name;
}
}
You can also do "GetCustomMember" which is like __getattribute__. But for this
one what you really want to do is inherit directly from the DynamicObject class
and override TryGetMember. Then it'll work not only w/ Python but w/ other DLR
based languages as well (e.g. C#, VB.NET, IronRuby, etc...).
