The wiki page for "5D Brainfuck with Multiverse Time Travel" claims that `(-^.[.]),[,]` is "cat, but faster." But it seems to me that the `.` would never print anything, because the lower universe contains no memory pointers at that point — the only one traveled to the upper universe as a result of the preceding `^` instruction (so now the upper universe contains two memory pointers). Am I missing something or does that example not really work as advertised?
