    A generator expression may be used in Python versions >= 2.4 which gives lazy evaluation over its input, and can be used with generators to iterate over 'infinite' input such as the count generator function which returns successive integers:

  3. Async/await - Wikipedia

    en.wikipedia.org/wiki/Async/await

    First, the async keyword indicates to C# that the method is asynchronous, meaning that it may use an arbitrary number of await expressions and will bind the result to a promise. [1]: 165–168 The return type, Task<T>, is C#'s analogue to the concept of a promise, and here is indicated to have a result value of type int.

  4. Control flow - Wikipedia

    en.wikipedia.org/wiki/Control_flow

    Sometimes within the body of a loop there is a desire to skip the remainder of the loop body and continue with the next iteration of the loop. Some languages provide a statement such as continue (most languages), skip, [8] cycle (Fortran), or next (Perl and Ruby), which will do this. The effect is to prematurely terminate the innermost loop ...

  5. Continuation-passing style - Wikipedia

    en.wikipedia.org/wiki/Continuation-passing_style

    [1] [2] John C. Reynolds gives a detailed account of the numerous discoveries of continuations. [3] A function written in continuation-passing style takes an extra argument: an explicit "continuation"; i.e., a function of one argument. When the CPS function has computed its result value, it "returns" it by calling the continuation function with ...

    Available in BSD Unix, and almost anything else with a TCP/IP protocol stack that either utilizes or is modeled after the BSD implementation. A variation on the theme of polling, a select loop uses the select system call to sleep until a condition occurs on a file descriptor (e.g., when data is available for reading), a timeout occurs, or a ...

    This is a feature of C# 2.0 and .NET Framework 2.0 See also: Generic programming Generics (or parameterized types, parametric polymorphism ) use type parameters, which make it possible to design classes and methods that do not specify the type used until the class or method is instantiated.

  9. List comprehension - Wikipedia

    en.wikipedia.org/wiki/List_comprehension

    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.
