Jonathan Blow demos his game development tech: own programming language/compiler (eurogamer.net)

It looks like a mixture of C++, Pascal, Haskell. Ugly to my taste. Reminds me of PHP and certain Operating system named after a building of worship.

Well done.. i watched his language conception videos. He really thought this well through. Its not tailored to the task is made for - relatively quick writing highly performant game code.
