I haven’t worked on a cypher suite before, but I have worked on voting software for a preferential system, and that was very goto heavy. This was because a goto-based flow was easier to match to the algorithm defined in legislation - each set of lines in the code were commented with the relevant clause in the legislation. Translating an algorithm into, say, a more functional style increases the risk of a small deviation from the algorithm in an edge case which would be very hard to find by testing because you don’t necessarily know the edge is there.
