D slicing syntax and indexing isn't able to represent what you can in Python,
where you can store the last index in a variable:
last_index = -1
a = ['a', 'b', 'c', 'd']
assert a[last_index] == 'd'
In D you represent the last index as $-1, but you can't store that in a
variable.
Sure you can:
last_index = a.length - 1;
