Such slice also needs a way to specify the end of the enclosing interval, the $ syntax.
Slice may enjoy a lot a third optional argument (default = 1), that represents the stride.

(In the Chapel language all this is generalized into the concept of Domain, that I think is a good language feature to introduce in D).
