In your C++ example you're giving `std::mismatch`, which is a generic algorithm. If you're so inclined you could provide a wrapper that has the same interface as the Go example, but you're comparing apples to oranges. I'd argue that `std::mismatch` is much _more_ pragmatic than the Go example, in that I can use it to check any lists of user defined types.

In reality, these two methods do completely different things. `std::mismatch` is a completely generic algorithm that 'returns the first mismatching pair of elements from two ranges', which can be used for much more than `strings.HasPrefix`.
