Talk:Reversible Brainfuck

From Esolang

A suggestion for increased symmetry, similar to Kayak: Let the . command zero its cell, and let the tape be left-infinite as well. This way any program which ends with a cleared tape can easily be turned into a reversed program. --Ørjan 17:27, 30 Dec 2006 (UTC)

That would mean that . would be irreversible unless the output were taken into account (which is how Kayak does it), so there's an issue with how much of the system is looked at when considering reversibility. I do like additional symmetry, though. --ais523 11:48, 3 Jan 2007 (UTC)
