TīmeklisPurity and lambda calculus were baked into the language from the start. Lazy evaluation largely obviates the need for macros. The Hindley-Milner type system underpinning Haskell 98 lets us write code without a single type annotation. It feels like Lisp, yet an efficient type inference algorithm means the compiler rejects badly typed … TīmeklisLambda Calculus expressions are written with a standard system of notation. It is worth looking at this notation before studying haskell-like languages because it was the inspiration for Haskell syntax. Here is a simple Lambda Abstraction of a function: λx.x. The λ (Greek letter Lambda) simply denotes the start of a function expression. the promised land mansion
