I've just looked a bit at these APL-type languages.  In Nial, for
example, everything is an array.  It seems that they consider numbers,
strings, etc., to be zero-dimensional arrays, with the convention that a
zero-dimensional array is a scalar.

I don't think we need that convention here, scheme has perfectly good
non-array objects.
