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.

Classes are self-describing user-defined reference types. Essentially all types in the .NET Framework are classes, including structs and enums, that are compiler generated classes. Class members are private by default, but can be declared as public to be visible outside of the class or protected to be visible by any descendants of the class.
The lambda expression being analyzed. The table parameter lists for names. The table of values for parameters. The returned parameter list, which is used internally by the; Abstraction - A lambda expression of the form (.) is analyzed to extract the names of parameters for the function. {-- [(.
Here, the list [0..] represents , x^2>3 represents the predicate, and 2*x represents the output expression.. List comprehensions give results in a defined order (unlike the members of sets); and list comprehensions may generate the members of a list in order, rather than produce the entirety of the list thus allowing, for example, the previous Haskell definition of the members of an infinite list.
The types of objects that can be iterated across (my_list in the example) are based on classes that inherit from the library class ITERABLE. The iteration form of the Eiffel loop can also be used as a boolean expression when the keyword loop is replaced by either all (effecting universal quantification) or some (effecting existential ...
In the above, the variable a initially refers to a lazy integer object created by the lambda expression -> 1. Evaluating this lambda expression is similar [a] to constructing a new instance of an anonymous class that implements Lazy<Integer> with an eval method returning 1. Each iteration of the loop links a to a new object created by ...
(Here we use the standard notations and conventions of lambda calculus: Y is a function that takes one argument f and returns the entire expression following the first period; the expression . ( ) denotes a function that takes one argument x, thought of as a function, and returns the expression ( ), where ( ) denotes x applied to itself ...
It is strongly influenced by Python, C#, Eiffel, Objective-C, and other programming languages. [3] It supports both static and dynamic typing. [4] [5] It has support for unit tests and contracts. [4] It has lambda expressions, closures, list comprehensions, and generators. [6]
