I think we need to draw a distinction between variables that are used on the same line where they’re bound, and variables that live longer. Naming things firstpar, secondpar, thirdpar is silly in this context, because if they had single-letter names, the names would still be right there on the same line where they’re used. But I actually did look up Pochhammer there, and got a reminder of its definition as the first search result, and I couldn’tve done that if the TeX symbol were used instead.
