I just have one quation about
https://github.com/scheme-requests-for-implementation/srfi-268/compare/draft-2..draft-3

In this example:
==========================
<p>and this literal for a three-dimensional array:</p>
<pre>#af32(2 3 4)
   (((1 2 3 4) (5 6 7 8))
    ((9 10 11 12) (13 14 15 16))
    ((17 18 19 20) (21 22 23 24)))
</pre>
==========================
should the entries be floating-point numbers?
