I'm implementing [Befunge-98 in Ruby](https://github.com/Nakilon/befunge98). The problem is that according to the Lahey-space wrapping the backtracking a long delta is not the same as circling around a sphere -- it...

The [program flow](https://github.com/catseye/Funge-98/blob/master/doc/funge98.markdown#direction-changing) section states that `h` is delta

In Trefunge-98 source, the ascii form feed increments the z coordinate, which is equivalent to a 'go low' instruction. This is all the specification says. I'm imagining a 3-dimensional Funge-Space...
