Functional Programming in C#

The core functions of FP

Function/signature/aka	Description (book location)
Return T → P<T> point, lift, pure	Takes a value of type T and “lifts” it into a “structure” with the given T as its “inner value” (sections 4.3 and 8.3).
Map F<T> → (T → R) → F<R> fMap, project, lift; Select in LINQ	Takes an F<T> (a functor over T; that is, a structure whose inner value(s) have type T) and a function T → R, and returns an F<R> whose inner value(s) are the result of applying the given function to the inner value(s) of the given functor (section 4.1).
Apply A<T → R> → A<T> → A<R>	Takes an applicative functor A<T → R> wrapping a function, and an A<T> wrapping an argument, and returns an A<R> wrapping the result of applying the wrapped ...
