i haven't had the time to study the language in detail, but a
few thoughts have been running in background.

as a first program, i thought i'd attempt an implementation of
conway's game of life. the way i want to think of this is that
there's a rectangular area, infinite in the east and south
directions, and instructions for reading and writing cells
in the area.

it occurred to me that 'r' and 'w', if confined to operations
on this "data plane", could be reversible. r takes a coordinate
and leaves the character at that location on the stack; w takes
a coordinate and a character and places the character at that
location on the plane.
