in reply to Multidimensional regular expressions

I'd like to add that just before posting this I was starting with some ideas regarding Quantum::Superposition and the any(),all() junctions to express what might happen if the \[{} sequence left the engine at a non-terminal. I don't yet know how that additional functionality should be expressed or what it would mean.

__SIG__ use B; printf "You are here %08x\n", unpack "L!", unpack "P4", pack "L!", B::svref_2object(sub{})->OUTSIDE;
