In computer programming, an anonymous function (function literal, expression or block) is a function definition that is not bound to an identifier. Anonymous functions are often arguments being passed to higher-order functions or used for constructing the result of a higher-order function that needs to return a function. [ 1 ]
Expressions, such as x <= y, a = b + c, or even lambda functions and other complex forms can be created dynamically using expression trees. Much of the functionality is provided by static methods of the class System.Linq.Expressions.Expression. There are also various new classes in that namespace that represent the expressions and partial ...
It also defines a set of method names (called standard query operators, or standard sequence operators), along with translation rules used by the compiler to translate query syntax expressions into expressions using fluent-style (called method syntax by Microsoft) with these method names, lambda expressions and anonymous types.

In this example, the lambda expression (lambda (book) (>= (book-sales book) threshold)) appears within the function best-selling-books. When the lambda expression is evaluated, Scheme creates a closure consisting of the code for the lambda expression and a reference to the threshold variable, which is a free variable inside the lambda expression.
WASHINGTON (Reuters) - U.S. manufacturers are optimistic that the sector will emerge from a prolonged recession next year, though capital expenditure growth was likely to fall short of 2024's pace.

C# 3.0 introduced type inference, allowing the type specifier of a variable declaration to be replaced by the keyword var, if its actual type can be statically determined from the initializer. This reduces repetition, especially for types with multiple generic type-parameters , and adheres more closely to the DRY principle.
