Are there any benefits to using a C# method group if available?

Question

When dealing with something like a List you can write the following:

list.ForEach(x => Console.WriteLine(x));

Answer 1

As others have noted, there is an extra unnecessary layer of indirection induced by the lambda. However, there are subtle language differences as well. For example, in C# 3 generic type inference works differently on M(F) than on M(x=>F(x)) when attempting to perform return type inference.
