def B {
list<int> X = [10, 20, 30, 4, 1, 1231, 20] [2-4,2,2,0-6];
}
... which isn't particularly useful, but more is to come.

Add initial support for list slices. This currently allows you to do stuff
like this:
def B {
list<int> X = [10, 20, 30, 4, 1, 1231, 20] [2-4,2,2,0-6];
}
... which isn't particularly useful, but more is to come.
