Static arrays are always allocated at run-time. It's the size of 
the array that must be known at compile-time (in this case via a 
template parameter).

What's the advantage (or the essential difference) of
     auto data = static_array!(int, 5);
instead of
     int[5] data;
? Just asking ;) but it's good to play.

What does not compile on my end are the run-time parameters (3) 
and (2)...?
