How to call a function in main()?

If it's a sorting routine, then it probably sorts data in-place, 
so it's more clear to not return data. If the function copies 
inside the input data before sorting it, then it's right to 
return the result.
That's why in Python sort returns nothing and sorted() returns 
data.
The D sort finds a third way, returning something that is not 
exactly the input data :-)
