Since this is a "Learn" part of the Foruam, be careful with 
"-boundscheck=off".

I mean for this little snippet is OK, but for a other projects 
this my be wrong, and as it says here: 
https://dlang.org/dmd-windows.html#switch-boundscheck

"This option should be used with caution and as a last resort to 
improve performance. Confirm turning off @safe bounds checks is 
worthwhile by benchmarking."
