Best way to link to another package in doc.go files

What's the best way to link to a doc in another package when writing package docs in a doc.go file? Unfortunately, the normal approach of referencing an imported package doesn't work in doc.go files since unused imports aren't allowed.

// Package foo docs in a doc.go file// foo uses [bar.Bar] types for doing things.package fooimport "foo.com/jonathan/godoctest/bar" // Unused import error here

Using a fully qualified path does work, but doesn't make for the most readable docs:

// Package foo docs in a doc.go file// foo uses [foo.com/jonathan/godoctest/bar.Bar] types for doing things.package foo

Any ideas for a workaround?
