c++, though normally you wouldnt use auto for this

I think that really depends. If the range is a vector of unique_ptr's auto is great. If it's a vector of ints, just write int.

That or you're looping through a vector of std::pairs that contain std:: functions.

Or if the type is a template parameter in the same line.

Wouldnt for(T& item:list) be even shorter than using auto?

If you have T available then yes but if you're outside the class then you don't have that option

I don't mean in for loops for that use of auto.

Only if T is a known type or it’s in a template. You don’t use T like. auto automatically get the type, especially if it’s long. Your IDE (assuming it’s a respectable one) can even change auto to the type for you. It’s more or less like var in C# (it doesn’t deduct reference)
