Is this frame safe to ride?

The guy at the shop I was at today to sort out my rear hub told me that it most probably wasn't too dangerous to ride, at least for a short period of time..but I'm still sceptical, I might just take your advice and bin it at once..

I already have a brake at home, so as soon as I get the new frame I'll mount it. But now that I know how to skid properly it's not a big problem to ride brakeless (yeah, until this happens that is)..
I was lucky enough to not get ANY marks on myself though, but I think it's once in a lifetime kind of luck..=P

The problem is that its impossible to tell just how long it could be before it breaks, it might last weeks, or it might leave you with half your face distributed across the tarmac tomorrow, totally not worth the risk, ever!
With all due respect if you knew how to skid properly and control your bike effectively you wouldn't have gone head on into whatever it was you hit, I rode brakeless on my bmx for 7-8 years and only ever had one crash on the roads which was due to my own stupidity not lack of brakes, stick a brake on until you are so confident brakeless that you don't even contemplate touching your brake in any situation, then maybe its time to think about doing the whole brakless shizzle if you want to.
