I see that this is used in Python's strings, to get a char from the end of
the string. Would there be any drawback in implementing the same thing in
D's arrays ? Something like :
array[-x] = array[array.length - x]

The drawback I can see is that it needs a runtime check every time an 
array is indexed. I would classify that as a stopper. Instead, in D, you 
can write:

array[$-1]

You can always fake it. In the following code i can be either positive or
negative:
array[(i+$)%$]
