I now program in C# for a living but before that I programmed in python for 5 years. I have found that I write C# very that most examples I see on the web. Rather then writing things like:

foreach (string bar in foo)
{
    //bar has something doen to it here
}

I write code that looks like this.

foo.ForEach( c => c.someActionhere() )

Or

var result = foo.Select( c =>
                {
                    //Some code here to transform the item.
                }).ToList();

I think my using code like above came form my love of map and reduce in python while not exactly the same thing the concepts are close.

Now it's time for my question. What concepts do you take and move with you from language to language. That allow you to solve a problem in a way that is not the normal accepted solution in that language?
