@donutloop, okay, I will add the documentation.

@donutloop Hi donutloop. there is copylocks warning in Optional struct methods(see blow picture),

To fix it. Can we change field mu to *syncRWMutex, and init mu in construct methods(Empty, Of, OfNullable)?, see blow picture, I have updated it in v2 branch. What do you think of it?

[donutloop]

@duke-git Yes, I concur that the optional container is meant to be circulated. Moving forward, I'll make sure to execute the vet command prior to submitting a PR. Normally, I adhere to this practice, is this vet check already part of the code pipeline? If not, we can setup a code action in GitHub for it.

Was already late here

@donutloop, now this vet check isn't part of the code pipeline. It's my local editor check. Yeah, we can add a vet check step to the github action file like this:, if ok, I will add it now.
