Dear All,

Here’s a beginner's question about How to Design Programs.

HtDP puts great emphasizes on data, and it forces the reader to think about
data types by writing signatures. Then what not use a typed language so
that it is forced by the language itself? Or did I misunderstand the
purpose of the authors?

Thanks and regards,
