A preliminary, experimental and only minimally tested of the
"crunch" mini-compiler is now available in the eggs repository.
It compiles a statically typed and heavily restricted dialect of
Scheme into C++. Crunch can be used to generate standalone
programs without any external dependencies. Alternatively,
you can embed sections of crunched code in normal Scheme
programs. The idea is to write sections of performance-critical
number crunching code and use them with minimal hassle.

This release is likely to contain many bugs and inusfficiences.
Feedback is (as usual) welcome.
I tried to compile something like this:
(crunch
(define (f32vector+ va vb)
(let* ((n (f32vector-length va))
(vr (make-f32vector n 0)))
(do ((i 0 (add1 i)))
((>= i n))
(f32vector-set! vr i (+ (f32vector-ref va i)
(f32vector-ref vb i))))
vr)))
but got the following instead:
Error: illegal foreign return type `f32vector'
Is this currently not supported or is something else misssing?
