1# https://golang.org/issue/46141: 'go mod tidy' for a Go 1.17 module should by
2# default preserve enough checksums for the module to be used by Go 1.16.
3#
4# We don't have a copy of Go 1.16 handy, but we can simulate it by editing the
5# 'go' version in the go.mod file to 1.16, without actually updating the
6# requirements to match.

14# produces a different error for a different module.
