const return types, or lack thereof
From what I gather, functions return temporaries which don't need to be const (I assume making it const would use more processing) except for cases where returns are pointers or references.
I have no problem understanding why pointers would warrant such sensitivity. It's a common algorithm to move a pointer instead of calculating the new position from the start every-time. So just as easily as they can moved appropriately, they can be moved inappropriately.
Where I don't understand is the supposed need to make references const, I thought references were basically pointers that couldn't change once initiated and were required to be initiated. If something can't be change inherently, where's the need to repeat the requirement (and add processing) ?
Sorry if I'm duplicating an issue, I couldn't find one alike with the search results I got from
