Quick research: http://racket-lang.org/ http://planet.racket-lang.org/ (the "CPAN" of Racket) http://en.wikipedia.org/wiki/MongoDB http://docs.racket-lang.org/continue/index.html (web apps) https://github.com/dmacdougall/spin (RESTful web apps) http://en.wikipedia.org/wiki/Datalog

The shell commands of Racket could be used for (native compiled) batch files.

Some real world applicatons: http://www.mail-archive.com/users@racket-lang.org/msg07436.h...

The only thing I miss is a sophisticated GUI editor like in Delphi Pascal. MrEd is similar but only supports the basic GUI components (labels, buttons, ...). I hope composed components (tables ...) will come in future.
