While I would personally prefer to have an operator for the slicing
opeeration, I'm not willing to spend time arguing about it. So, +1 to
implement the subset operation as the function slice(), and defer having
an operator until later.
In some ways, it makes more sense to talk about additional operators in
the context of also adding them to intarray, and I don't want to go
there yet.
