Does this issue reproduce with the latest stable release?

Yes

What did you do?

exec cue get go --local .
grep field1 x_go_gen.cue
-- cue.mod/module.cue --
module: "example.test"
language: version: "v0.10.0"
-- go.mod --
module test
-- x.go --
package x

type X struct {
    Field1 *Y        `json:"field1"`
    Field2 int    `json:"field2"`
}

type Y struct {
    a int
    //B int
}

func (y *Y) UnmarshalJSON(data []byte) error {
    return nil
}

func (y *Y) MarshalJSON() ([]byte, error) {
    return []byte("true"), nil
}

What did you expect to see?

PASS

What did you see instead?

FAIL: /tmp/testscript2616510834/-/script.txtar:2: no match for `field1` found in x_go_gen.cue

Additional notes

If I uncomment the //B int line, the test passes.
