In fact, if you use a Haskell IDE, a text editor with a Haskell mode or a Haskell pretty-printer, it will actually be displayed like this: morph (λx → 1 + x) l .

TīmeklisA lambda calculus term consists of: Variables, which we can think of as leaf nodes holding strings. Applications, which we can think of as internal nodes. Lambda abstractions, which we can think of as a special kind of internal node whose left child must be a variable. (Or as a internal node labeled with a variable with exactly one child.) TīmeklisLambda calculus is a framework developed by Alonzo Church in 1930s to study computations with functions. Function creation − Church introduced the notation λx.E to denote a function in which ‘x’ is a formal argument and ‘E’ is the functional body. These functions can be of without names and single arguments.

TīmeklisThe lambda-calculus lies at the very foundations of computer science. Besides its historical role in computability theory it has had significant influence on programming language design and implementation, denotational semantics, and domain theory.
