Wow, thanks a lot, $ looks much better. I ditched | and was struggling with / last several days. It is doable, and Hexagony is not so bad actually - / sends it to the end
of polyglot, where fixing it can be almost fully automated. But it will break on any edits, and it is better to keep current Hexagony solution anyway.
After cursory look: $ is exit in Agony, but it can be skipped with () or []. $ is start for SNUSPs, and the only way to redirect
SNUSPs from the first line is \ because SNUSP IP does not wrap. \ is exit in axo, but axo can be sent down with %. So it looks doable.
