Racket 5.1

Racket^* 5.1 has been released with a massive GUI rework which leads to a fact that it doesn't look like crap on Linux anymore. Go grab it here: http://racket-lang.org and start programming something useful. 

___________________
[*] Racket is a Scheme influenced JIT-compiled programming language with robust metaprogramming and DSL creation facilities that allows to write procedural, functional, object-orientated, lazy evaluated and statically typed code. Combined with a rich set of libraries for GUI, multithreading, network and shell programming it makes Racket a perfect tool for both education and writing real world highly scalable ENTERPRISE solutions.

On the GUI side, the remaining 22,000 lines of Racket code replace similar C++ code that binds to three different toolkits. The set of underlying toolkits has changed, and a few eventspace tricks are new, but the approach is essentially the same as before. The code is nevertheless much more compact, because (no surprise) Racket is better than C++.
