AnimalMuppet on Pedagogical Downsides of Haskell

Comment on Pedagogical Downsides of Haskell parent

I see. The language spec explicitly talks about the machine. That's not nothing.

In practice, though, when I have some piece of memory-mapped hardware attached, and I want to talk to it, in C I can say:

  *(uint32_t*)0xF00BA4 = 0x0102ABCD;

or whatever I need to flip the bits. C lets me actually control the whole machine. Whereas Haskell... I don't know, but I suspect it lets me actually use the physical machine a lot less.

There might be a cleaner way of doing it, but

    do
      let ptr :: Ptr Word32 = nullPtr `plusPtr` 0xF00BA4
      poke ptr 0x0102ABCD

should have you covered.

Really? Can you run micro-ops?

You know you can write C inside Haskell, right?

Like, there's literally nothing stopping you. You can use FFI, and you can also write C inline.

You can have the best of both, if you want.
