            // basically, you can write a static method in a static class, and tell C# to pretend that it's actually
            //   defined on the class of one of its first parameter.
            // it's "syntactic sugar" but does LOOK like you get to modify any class in C#
            // and add your own methods.

            // LINQ is just a big pile of overloaded extension methods defined for the IEnumerable<T> interface

            // three types of LINQ methods
            // 1. the ones that return a new IEnumerable collection (they never modify the original collection)
            //    they don't execute "yet" - they use deferred execution.
            // 2. the ones that return any concrete value - like Average, First- do not use deferred execution
            // 3. things like ToArray, ToList. these return collections that need to be "all there"
            //     so they also don't use deferred execution.
            //    "ToList" lets you effectively force execution of type-1 methods whenever you want.

            // - Select: maps each element to something new
            // - Where: filters the collection according to some condition

            // - Distinct: filters out duplicates
            // - Skip: skips n elements
            // - Take: skips AFTER n elements

            // - Count: counts how many items (match a condition)
            // - First: returns the first item (matching a condition)

            IEnumerable <string> noNulls = list.Where(x => x != null);
            var lastChar = noNulls.Select(x => x[x.Length - 1]);
            var upper    = lastChar.Select(c => c.ToString().ToUpper());

            string first = upper.First(); // we get the first element of that new collection...
            // it processed the first item but hasn't looked at the others yet.

            List <string> list2 = upper.ToList(); // now it has processed all of the items.
