package p

type T[A, B any] struct{}

func _() {
        type _ T[int]
}

produces two errors:

testdata/manual.go2:13:16: cannot infer B (testdata/manual.go2:10:11)
testdata/manual.go2:13:16: got 1 arguments but 2 type parameters

One would suffice.

Type type-inference has been removed. We now get the expected single error (playground). Closing.
