+Lambda Rules:
+
+(1) x ϵ V => x ϵ Λ
+(2) M,N ϵ Λ => (M N) ϵ Λ (Application)
+(3) M ϵ Λ and x ϵ V => (λx.M) ϵ Λ (Abstraction)
+(4) No further Terms in Λ existent
+
+Examples:
+
+(λx.(λy.x)) ≡ λx.λy.x ≡ λx y.x ≡ false
+(λx.(λy.y)) ≡ λx.λy.y ≡ λx y.y ≡ true
+λx.λy.((x y) false) ≡ λx y.((x y) false) ≡ and
+
+Syntax:
+
+(λx . (λy.x)) ≡ λx.λy.x ≡ λx y . x ≡ false
+true: x y = x;
+
+(λx.(λy.y)) ≡ λx.λy.y ≡ λx y . y ≡ true
+false: x y = y;
+
+λx.λy.((x y) false) ≡ λx y.((x y) false) ≡ and
+and: x y = (x y) false;
+
+id: x = x;
+
+greet: x = say (~ "Hello " x);
