Ah, sorry, I completely missed that they were different kind of arrays,
which was of course the point of the example. But as far as I know,
there is no way to remove code duplication in this case, barring tucking
the code 'away' to another function or doing tricks with
Obj.magic. (Well, unless the GADT support brings something to new the
table related to this, but I wouldn't know.)
