patch for the array initialization

Untested patch for the array initialization - if there are several (patch uses
10, could be say a param) consecutive same elements in the ctor, we can just
use a loop instead, and let it to the compiler to decide if it will want to
unroll it or not.  I guess the initializer_list would need similar treatment.
