Language::Befunge::Wrapping::LaheySpace - a LaheySpace wrapping
LBW::LaheySpace implements a wrapping as defined in befunge specs - ie,
when hitting a bound of the storage,
the ip reverses and backtraces until it bumps into another bound,
and then it reverses one last time to keep its velocity.
Creates a new LaheySpace wrapping.
$storage according to this module wrapping algorithm.
See DESCRIPTION for an overview of the algorithm used.
$ip is already out of bounds,
it has been moved once by LBI.
As a side effect, $ip will have its position changed.
