Snow is a place to share Scheme programs, libraries and data. Currently we host only R7RS libraries, though we may expand to more dialects in the future.

I tried to run the trivial program
(define ! (n) (if (< n 2) 1 (* n (! (1- n)))))
(display (! 10))
, but got an error message about not being able to enlarge memory arrays.
