Well, actually what I meant was I've never used properties at all and
didn't find any useful documentation. I had in mind a fairly draconian
configuration that made nearly everything readonly, though I suppose
that would become cumbersome within my own methods. And anyway it
doesn't really work for numpy arrays, since someone can always do b =
A.unwritable_array; b[i,j]=3. But set_yi is a bit ugly.
