Closers and decorators are very handy tools for simplifying interfaces and  
thereby avoiding duplication and inappropriate intimacy. I skipped the Python 
craze, so I don't know how people implement them in Python, but they look 
okay to me in Ruby and C#. C# 2.0 also has lexical closures and 
semi-continuations, btw. I haven't seen a need for them yet, but maybe Luis 
and the other programmers will in the next bugreport iteration.

.NET 2.0 has some specific changes in the structure to deal with dynamic 
languages, with IronPython's speed being a benchmark.

It's a matter of if you want the library consumable from *all* .NET languages 
and therefore be CLS-compliant, or if you just want to interoperate with C#. 
Choosing the later might screw you out of interoperating with 100%, say, boo. 
Then again, 100% interoperability might not be important depending on what 
your exposed API actually does.

I haven't used GTK#, but mono's WinForms implementation is coming along quite 
nicely. I can use Reflector and nunit-gui, which is about all I need :) 
MonoDevelop was still unusable the last time I checked. I really wish their 
dick-fight with SharpDevelop would end and they would just work from the same 
underlying codebase.
