I imagine this would still be useful if compilers like Haskell can produce intermediate code for what&#x27;s described in the book. Not sure if they do but I have an academic paper that created a G-machine to Forth (CPU) compiler for embedded Haskell. Made me think there was a G-machine output option.<p>Point being, plenty one can contribute to FP in terms of safety, performance, integration, and so on just knowing backends. Esp if more people do FP CPU&#x27;s.
