Template Haskell for faster linear interpolationAn application I’m writing requires a lot of linear interpolation of a function. There’s so much of it, in fact, that it was the biggest single contributor to the running time. In this article I show how I used Template Haskell to make it much faster and cut the overall running time of the application by about a third. To be clear about the problem, we have a list of points (which I’ll call the “t
