The intent of “just” looping in excess of the elements of v is not really expressed below. The implementation depth of the index is exposed (making sure that it would be misused), And that i outlives the scope from the loop, which may or may not be meant.

Just Consider: What code can the compiler make for setting up an arr wherever, In case the fourth object’s constructor throws, the code has to surrender As well as in its cleanup manner attempts to simply call the destructors on the presently-built objects … and a number of of These destructors throws? There is no satisfactory solution.
Consider putting just about every definition in an implementation source file within an unnamed namespace Until that is defining an “external/exported” entity.
