The other function is outside of time? Then, use, a few small extensions to the iota function can be made, but nothing major.

Also, I believe that diagonalising over language as a whole leads to results that are impossible to keep finite, as a large enough ¥ could just define some new function, similar to ¥, that could get it some more characters to use. It would be like defining rayo's function in rayo's function: rayo(googol) could refer to rayo(googolplex), leading to it just running away to the largest finite number, which is in essence, infinity.
