Taranovsky does give a Python implementation of his notation here, which implements a lot of different interesting functions for the notation. It may be worth perusing.

I believe Taranovsky's notation is probably theoretically implementable in Coq, but I imagine it may be very difficult. We haven't even defined an epsilon_0 function yet.
