After writing my note, I realized that the formulation above 
actually _should_ work now (though it shouldn't have worked 
before!).  Because, in effect, it's

matrix m = { <implicit list> }

and lists are supposed to be OK in that context.  I'll work on 
that.  (The trouble right now is that only named lists are 
accepted in that context.)

Yes.  Though we're not totally free of ad-hocery on lists just 
yet; but getting better.

Allin.
