I've got 3 minutes. I've spent more than 3 minutes searching, and I can't find a way to specify a version in an import (though you can tag the go version, you still can't tie the import to a specific tag or version or commit). Am I missing something? It seems the only way around this is to check out a point in time release and import that (which would solve the problem the article mentions). However, that's a workaround for a problem that package managers like NPM and RubyGems have trivially solved.
