Lambda Evaluator


This lambda evaluator will allow you to write lambda terms and evaluate (that is, normalize) them, and inspect the results.
(This won't work in Racket, because Racket doesn't even try to represent the internal structure of a function in a humanreadable way.)

*Abbreviations*: In an earlier version, you couldn't use abbreviations. `\x y. y x x` had to be written `(\x (\y ((y x) x)))`. We've upgraded the parser though, so now it should be able to understand any lambda term that you can.
*Constants*: (NOT YET IMPLEMENTED!) The combinators `S`, `K`, `I`, `C`, `B`, `W`, and `T` are predefined to their standard values. Also, integers will automatically be converted to Church numerals. (`0` is `\s z. z`, `1` is `\s z. s z`, and so on.)
