Now that #48094 is fixed, I'm running into another issue using generics, this time via go vet and whatever cmd/vet uses to import packages.

What version of Go are you using (go version)?

~/src/github.com/bcmills/unsafeslice$ gotip version
go version devel go1.18-144e0b1f6 Tue Aug 31 17:35:15 2021 +0000 linux/amd64

Does this issue reproduce with the latest release?

N/A

What operating system and processor architecture are you using (go env)?

What did you do?

In the root of the repository at bcmills/unsafeslice@849066c, run go test ..

What did you expect to see?

A successful test run, or a test failure, or a compile error indicating a problem in my code.

What did you see instead?

~/src/github.com/bcmills/unsafeslice$ gotip test .
# github.com/bcmills/unsafeslice_test
vet: ./safe_test.go:19:2: could not import github.com/bcmills/unsafeslice (cannot import "github.com/bcmills/unsafeslice" (unexpected kind tag in "github.com/bcmills/unsafeslice": 11), possibly version skew - reinstall package)

Everything else seems to work at that commit if I bypass vet:

~/src/github.com/bcmills/unsafeslice$ gotip test -vet=off .
ok      github.com/bcmills/unsafeslice  0.018s

This is because we've fallen behind in go/internal/gcimporter.

I can port the necessary importer changes.

go/internal/gcimporter: add support for importing parameterized types
b8420ba 
Port the necessary logic to go/internal/gcimporter from
cmd/compile/internal/importer/iimport.go to support type parameters.

This is a partial port of several compiler CLs: at least CL 319930,
CL 322609, CL 323029, CL 338192, CL 340251, and CL 340989. Because these
ports were not interleaved with the corresponding go/types API changes,
it is easier to just take the latest importer logic.

Notably, the equivalent of types2.AsTypeParam is not used. It should be
unnecessary.

Updates #48101
