[IronPython] IronPython and LINQ

[Keith J. Farmer]

Actually, these features are not dynamic in the "Python is a dynamic
language" sense.  There are no features which add new members to a type
at runtime, for example, nor is there any weak typing.  C# remains a
static, strongly-typed language.

Lambda Expressions -- this is syntactic sugar which allows a single
syntax to be compiled into either delegates or expression trees
Expression Trees -- simple object trees to encode an expression
Object Initializers -- syntactic sugar
Anonymous Types -- compiler-assisted type generation.  The type is
created by the compiler and given an unknowable name.
Type Inference -- again, sugar for "the type implied by the right hand
side of the assignment"
Extension methods -- more sugar.  barInstance.Method(baz) is compiled to
BarExtensions.Method(barInstance, baz)

.. None of these do anything that wasn't possible before.  They just
make doing it easier.

I see that in C# v3 have many dynamic language feature. eg:

Lambda Expressions -Pred<Customer> = |c| c.City == "London";
Expression Trees - Expression<Pred<Customer>> = |c| c.City == "London";
Object Intializers -Contact c = new Contact { Name = "Bill", Phone =
"..." };
Anonymous Types -new { Name = "Bill", Phone = "..." }
Type Inference --var c = new { Name = "Bill", Phone = "..." };
Extension Methods--static void Method(this IEnumerable<T> src)

what policy ms have in dynamic language between c# and IronPython.
