It’s pretty simple: your can define a Ruby method on any class/interface. The method will only be visible from Ruby unless the class is a Ruby dynamic object (implements IDynamicObjectProvider using Ruby binders). For such dynamic objects Ruby methods will be available when invoked from dynamic expression in C# 4.0. The methods are also invokable via ObjectOperations class in Hosting API.

I know in C# it can't be done obviously and as long as I stay in Ruby you can. I understand this may seem like straight-forward stuff.
