WebChurch booleans can then be encoded as lambdas that take two parameters in curried fashion and produce the correct branching behavior, while if-expressions are turned into applications of the church-boolean; i.e., (if b e0 e1) – > ((b e0) e1).. This behavior is almost correct, but to get it perfect we must consider evaluation-order and the possibility of side … WebApr 5, 2024 · Alonzo Church, the creator of the \(\lambda\) calculus, realized this and consequently set about to make a series of encodings of \(\lambda\) expressions …
