Sure, I saw that, it obviously works pretty good.

I think it's worth mentioning that D slices are similar in 
concept to Go slices.

In Python, lists are reference types too but slicing creates a 
copy (so, 'b = a' shares, while 'b = a[:]' copies.) JavaScript 
arrays are similar to Python in this sense.
C++ and Rust use distinct types for the resizable array and its 
view, and the view must not outlive the array.

D and Go slices have advantages but can be confusing. I don't 
have a solution, but if anyone is interested, the relevant 
discussions about slice confusion in the Go community apply to D 
slices as well.
