I've been working on DBM::Deep, a way to have P5's data structures
stored on disk instead of RAM. One of the major features I've been
adding has been ACID transactions.
I'm pretty sure it wouldn't be very feasible to do this natively in

Today on #perl6, Audrey, Stevan and I were talking about $repr. A
