In 2006 I decided to create a computer language suitable for web programming and other things. The language should run on .NET and be better than PHP, Ruby and Python.
In 2008 I published Clearlisp on SourceForge.net. It was mainly an exercise to implement a syntactically simple language using .NET reflection. The Arc language was published at the same time.
My next exercise was to use Lex and Yacc to create a syntactically complex language called Rabbit. Rabbit was meant to be the semi-colon and braces embracing alternative to Ruby and Python, for C-lovers only. It was faster than ClearLisp because it used dynamic methods.
What happened that I did not publish it?
Dynamic Language Runtime happened. Dynamic methods are not good enough anymore. Cached and jitted methods are way faster.
