Is it possible to set user rights for no user?

Hi,

I have certain parts of the model that I would like to keep secret to all users. Is that possible?

can-read: // nobody

Does not seem to work.
Oh and it is in interface data, so hiding is not possible either.

For that you can specify a contradiction with a stategroup:

{
	can-read: .'Lock'?'Always' where ( .'Lock'?'Forever' ) // always false
	'Lock': stategroup = 'Always' ( ) (
		'Always' { }
		'Forever' { }
	)
}

Ok, thanks! Could be shorter than this, but luckily this does not happen all that often.
