spinning up threads and context switching, just like the cost for everyone else?

  The Haskell version is provably going to work without issue when parrellelized (due to monoid laws), but I doubt the concurrency primitives in C is as trivially usable, and I expect no sane person would want to write that version.

    Why? This is not a hard problem and there's nothing wrong with parallelism in C. I'd much rather work on parallelizing the C code than deal with any amount of Haskell. I suspect there are more people who would agree with me than the total amount of people happy to write Haskell.

    OpenMP IS trivially usable.

    There's nothing stopping you from following the monoid laws in C. There is also nothing stopping you from breaking the monoid laws in Haskell.
