WebChurch booleans are the Church encoding of the boolean values true and false.

WebLambda-calculus can encode most data structures and basic types. For example, you can encode a pair of existing terms in the lambda calculus, using the same Church encoding that you usually see to encode nonnegative integers and boolean: $$\mbox{pair}= λxyz.zxy$$ $$\mbox{fst} = λp.p(λxy.x)$$ $$\mbox{snd} = λp.p(λxy.y)$$ WebDec 25, 2024 · Church encoding is a scheme by which any calculable operator and its data (operands) can be expressed purely in terms of functions. It has traditionally been explored mostly in the context of lambda calculus, but works well in concatenative languages, and - I imagine - Lisp, and combinatory logic. In fact, it works in.

WebChurch encodings are a very interesting development arising from lambda calculus. Church found out that every concept in programming languages can be represented using functions! everything from boolean logic, conditional statements, numbers (natural, integer, real, complex, imaginary), and even loops (infinite loops also)!
