FWIW, Tie::Math makes good use of it because writing tied, multi-dimensional
data structures is a pain in the ass. Its easier to handle: $tied{1,2,3}
than $tied{1}{2}{3}.
Its also smaller and faster than working with multidimensional data
structures.
As I'm more concerned about speed, size and ties than Unicode, I'd say leave
it.
