over the years i've had to translate a lot of code from academics/researchers into prod systems, and variable/function naming is one of their worst habits.

just because the function you're implementing used single-character variables to render an equation in latex, doesn't mean you have to do it that way in the code.

a particular peeve was when they make variables for indexed values named`x_i` instead of just having an array `x` and accessing the ith element as `x[i]`
