That were my first thoughts too when I saw this code - a function can
return a single list only - and Perl can't know how this list should
be divided in two or more arrays. One has to return a list of scalars
holding references to the appropriate arrays (or a single array whose
elements contain the references).
AFAICT from the PerlXS doc, RETVAL has a 'limit' of one value returned,
so RETVAL won't work in my 'envisaged' function, but it seems possible
to return any number of vars via stack manipulation (subject to size)
using the ST(n) array.
