scancheck is a linter to ensure the bufio.Scanner is used correctly. Currently, it only checks to ensure that callers to a scanner's Err() don't occur within the scanner's for scanner.Scan() loop.
This linter errs on the side of false-negatives, and currently doesn't handle the following scenarios
- a
bufio.Scannerbeing returned from a non-newfunction - aliased
bufiopackage - nested loops of different
bufio.Scannerinstances
