Bugfix slicing notation
Bugfix slicing notation

Slicing an array [5]string uses halfopen interval [a:b) notation,
ie. `a` is part of the slice, `b` is not.

array := [5]string{"a", "b", "c", "d", "e",}
slice := array[1:3]

slice starts at array[1], but ends before array[3], ie. it contains
array[1] and array[2] => []string{"b", "c",}
