Good point.
And there is another problem: one could expect
10 * [[1,2],[3,4]] to be equal to [[10,20],[30,40]]
and in this case 10 should be equal to [[10,0],[0,10]], instead of
[[10,10],[10,10]] or [[10]].
I dont see how to fix this.
Could be better to forget about fromInteger...

fromInteger x = [[fromInteger x]]
Wouldn't you want the expression
[[1,0],[0,2]] + 10
to yield
[[11,10],[10,12]]
instead of [[11]] ? I guess you would need some complicated machinery
so this is one thing you have to ignore to keep your otherwise nifty
instance nice and simple.
