A "transactional" generic DbHelper for LINQ to SQL

Here's a nice little helper for those who intend to use LINQ to SQL. It will allow us to write something like:

DbHelper.Insert<Student>(
    new Student()
    {
        FirstName = "Tanzim",
        LastName = "Saqib",
        Email = "me@TanzimSaqib.com",
        Website = "http://www.TanzimSaqib.com"}, true);    // Use Transaction?

Concise and elegant, isn't it? And what if we turn this around into an extension method, wouldn't it be yet another cool usage? Something like:

    new Student()
    {
        FirstName = "Tanzim",
        LastName = "Saqib",
        Email = "me@TanzimSaqib.com",
        Website = "http://www.TanzimSaqib.com"}, true
    ).Insert(true /* Use Transaction */);

Oh, how I love C#3 and LINQ....
