一种专为研究进化而设计的程序设计语言。

Handy is a LISP-like programming language, specially written to study the evolution of computer code. If you can write code to both set a question and test the validity of the answer, then you can use the Handy language to produce computer code that, when given the data representing the question, can produce the answer. Such programming tasks would mainly be complicated questions, such as: "is this a picture of a human?" or "given this message, what is the private PGP key needed to unlock it?"
