As far as I know it works. It's an old Oleg trick.

Then it probably does work.

The only drawback is that error messages may refer to Private.

As I found out when probing its security. "No instance for Moo.Private" shows up. I guess that's what happens when you hide stuff: you get told what stuff's being hidden. In some situations, that's insecure, but here it's ok. Cheers (and have fun in China, Lennart!) Conor
