I don't think its a loophole, It must be intentional.
Second way which is popular now, you can add the gmail ids in your circle and share a comment to the circle. This will send a invite to everyone in the circle :)
On your stream page just type a message in the share something box "Hi." for example. Then in the sharing selection box put in their email address. They'll get a message with a link to see what you shared with them and for whatever reason that seems to have a much higher success rate though it can still take several attempts at clicking the link in the email before they get the sign up instead of the we're full message.
Also, if you are sharing with a circle you have to make sure you check the little box during circle selection that says "Also email X people not yet using Google+" or they won't get the email.
About 90% of the people that I've sent invites to are signed up now.
