I do believe that, in any case, this form is best:

A thousand? !arr.empty instead of arr.length? Was that your point?
That short path better be correct path in most cases and this form is
exactly in the opposite direction: treating if (arr) as if(arr.ptr)
Not to mention the following "idiom":
if( arr !is null && !arr.empty )
