@ggicci - sorry had issues with my original PR: #90 and coverage.
Re-opened it and its now 🟢

Not sure if this is what you meant with:

Let's hide owl from the package users. We may create a name alias in httpin, e.g.
var ErrUnsupportedType = owl. ErrUnsupportedType

Let me know if you thought of it in a different way.

Thank you!

@ggicci - what are your thoughts about this change? Would be great for us if it could be merged and unblock us upgrading to the latest version.

Thanks!

It looks good to me. I will update ASAP.
