I have seen samples of closure from - http://stackoverflow.com/questions/36636/what-is-a-closure

Can anyone provide simple example of when to use closure?

Specifically, scenarios in which closure makes sense?

Lets assume that the language doesn't have closure support, how would one still achieve similar thing?

Not to offend anyone, please post code samples in a language like c#, python, javascript, ruby etc.
I am sorry, I do not understand functional languages yet.

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy.
