So the Haskell version really starts to unravel into exponentially bad performance pretty quickly. This can be seen by adding another example with one more 0 at the endpic.twitter.com/NTI4KQk6wa
I'm worried that the baby thinks people can't change.

I wonder if there’s a bug in the Haskell code. If you have different big O properties, it’s unlikely that’s due to language performance differences.
The code is in a gist, if you can find a bug be my guest.
Turn on bangpatterns and add “!” As a prefix to the arguments
This is the typical foldl problem I think.
So a pure foldl implementation was actually slower because apparently you can't use the `-fvectorise` flag with this.pic.twitter.com/yWKpqnajkW
Right but what about foldl’
Same deal. The original loop seems to have been the most performant thus far.pic.twitter.com/DkoSoxyiCu
I’ll mess with it tonight and see if I can get it to something reasonable without turning the code inside out. This is curious to me.
Let me know what you find, but so far seems in line with the general assertion from above.
By the way, this thread is probably the best thing I can point to now for why I am not interested in programming in Haskell :)
