The Dylan language spec has amazingly few edge cases. It allows a continuum of dynamic -> static typing and a range of functional <-> OO. With the right set of libraries it could be great in the scripting space as Python, but is also designed for building large systems that run fast.

I have been intressted in dylan for some time. Here is my take on it. Dylan is just an awesome language, you will have to learn some dylan to find out if you agree. It has great potential to be a dynamic language that is really really fast, the compiler and gc are already really good. Its a really intressting project to hack on, the compiler for example is written in dylan itself.

Its not ready to go into production use but if you want an awesome opensource project with loads of potential to hack on dylan might be just the thing.
