Folks may also be interested that this version, 6.0, supports Crunch(although Crunch itself has not been declared a 1.0 status, currently @ .993), which is a compiler for a statically typed subset of Scheme R7RS. (https://wiki.call-cc.org/eggref/6/crunch)

For an introduction:

CHICKEN is a compiler that translates Scheme source files into C, which in turn can be fed to a C compiler to generate a standalone executable. An interpreter is also available and can be used as a scripting environment or for testing programs before compilation.

I started playing with Chicken over the weekend because I was looking for a scheme that you could build binaries of and that had a lively ecosystem. I've really enjoyed it. So far I've mostly played with web stuff. Built a wrapper around makemkvcon for ripping some dvds I've been meaning to rip that'll do a little bit of automatic naming of output using the tv db.

I was slightly worried that I'd start using v5 and then v6 would come out but it looked like they'd been working on it for a while so I figured I'd have some time on v5. Turns out I was wrong!
