Hello,
I'm wondering if there exists any writing which approaches learning a functional language (Lisp, Scheme, Haskell, whatever) from the perspective of creating real applications in it; something similar to the book Beginning Python, which acquaints you with that language and then walks you through creating a simple GUI app, CGI bulletin board, arcade game, etc. with it.
“Please don't assume Common Lisp is only useful for Databases, Unit Test Frameworks, Spam Filters, ID3 Parsers, Web Programming, Shoutcast Servers, HTML Generation Interpreters, and HTML Generation Compilers just because these are the only things happened to be implemented in the book Practical Common Lisp.—Tobias C. Rittweiler, Lisp Programmer
