@mariuspavelnistor thanks for reporting the issue. I agree this can be better handled in the Go generator similar to what we've done in other generators.

May I know if you have time to contribute the fix? I can show you some good starting points to fix the issue (the fix can be as simple as adding/copying a few lines)
