Wouldn't the normal implementation for == check lengths? Edit: Never mind, it doesn't: https://github.com/golang/go/blob/d28bf6c9a2ea9b992796738d03eb3d15ffbfc0

Wouldn't the normal implementation for == check lengths? Edit: Never mind, it doesn't: https://github.com/golang/go/blob/d28bf6c9a2ea9b992796738d03eb3d15ffbfc0b4/src/internal/bytealg/compare_generic.go https://github.com/golang/go/blob/d28bf6c9a2ea9b992796738d03... But checking lengths doesn't really help you: it only tells you when strings are not equal, and you would still have to walk the string to see which one is larger/smaller.
