Lambda the Ultimate

Cyclone is a type-safe dialect of C that incorporates a number of features from functional languages, including parametric polymorphism (ML-style, not C++), datatypes, and pattern matching. It also includes a number of features necessary to make C safe, such as fat pointers, tagged unions, and region-based memory management.

We've just put out a new release (1.0) and a new web site: http://cyclone.thelanguage.org

What I find most interesting here is that the difference between yield and "inline" is this negligible, which explains why Ruby users are so enamored with the feature.

That stated, the runtime wonk in me would love for some Ruby expert out there to explain the underlying reasons why yield is so much faster than Proc.call.

I can guess, but I'd rather be told.

Don Box does some experimenting...
