One context where I think it often makes sense is for integral types, e.g., for things like: auto len = aArray.Length(); auto display = GetStyleDisplay()->mDisplay; It can save having to look up whether aArray.Length() returns size_t (I sure hope it does, though) or whether mDisplay is uint8_t or uint16_t. That said, I do agree that using auto often obscures information. -David -- 𝄞 L.
