Is this the way one should implement *really* dynamic arrays: in which one can remove or insert elements and still have index and count corrects?
Are there other methods than moving all elements of higher index up or down? If no, is the correct method analog to the above loop? (But inside a unique dynarray)?
Or would it be better to implement such semantics from static arrays directly?
