I want to use modified module for troubleshooting. In 1.10 without modules I would cd into ~/go/src/github.com/rivo/tview, make modifications there and, if everything is ok, git commit && git push to upstream.
With modules, there is now ~/go/pkg/mod/github.com/rivo/tview@v0.0.0-20200219210816-cd38d7432498 and it is read-only.
How do people fix bugs in go modules to send upstream?
