@freemo Agree, #programming in #haskell is exhilarating. One of my favourite papers ever on applying #haskell for fun and profit: "Exploiting vector instructions with generalized stream fusion" by Geoffrey Mainland et al. 2013 https://dl.acm.org/doi/10.1145/2500365.2500601 where the authors "describe a stream representation suited for efficient computation with SSE instructions" which compare favourably to C++ implementations.
