new array without auto-initialization

[Joseph Rushton Wakeling]

Hello all,

Suppose I create a new dynamic array:

     auto arr = new int[10];

If I recall right, the values inside arr will be auto-initialized to int.init 
(which is 0).

Again, if I recall right, there's a simple way to increase performance by not 
auto-initializing the values, but I can't remember what it is.

Yes, I could use uninitializedArray/minimallyInitializedArray, but I seem to 
recall there's another way that follows the above syntax (or am I misremembering 
and just thinking of declared values?).

Thanks & best wishes,
