Details:

Kawa truncates integers when storing into byte arrays:

(scheme-implementation-version) => "1.13.1 (revision 7422)"
(define v (byte[] length: 1))
(set! (v 0) 128)
(v 0) => -128


The same happens for s8vectors.
It would be nice if the value would be checked and signal an error
if it is not in the [-128, 127] range.
