longDescription = '' | ||
LambdaLisp is a Lisp interpreter written as a closed untyped lambda calculus term. | ||
It is written as a lambda calculus term LambdaLisp = λx. ... which takes a string | ||
x as an input and returns a string as an output. The input x is the Lisp program | ||
and the user's standard input, and the output is the standard output. Characters | ||
are encoded into lambda term representations of natural numbers using the Church | ||
encoding, and strings are encoded as a list of characters with lists expressed as | ||
lambdas in the Mogensen-Scott encoding, so the entire computation process solely | ||
consists of the beta-reduction of lambda terms, without introducing any | ||
non-lambda-type object. | ||
